Transportation to Tempe

I need to rent a car for Megan to get to school.  Luxury for Less charges $21.59 plus 14 cents per mile.   Cheap Chariots charges $18.25 plus 22 cents per mile.   At first glance it looks as if I should go with Cheap Chariots.  Still, I'm concerned about the per-mile charge because Megan does a lot of driving. It is more than 30 miles to ASU from my house alone.

1. Determine how many miles would Megan have to drive to make the cost of renting a car from Cheap Chariots the same as the cost of renting a car from Luxury for Less?
2. Explain which company you think I should rent a car for Megan’s from and why you think it is a better deal.  
3. Please read the problem carefully. Be sure that you give all the details of your solution, including all the comparisons that you make in order to determine the answer.

Horton's Clover Hunt

Horton's Clover Hunt  

Who doesn't love the story Horton Hears a Who! by Dr. Seuss. For those of you who aren't familiar with this particular tale, Horton the elephant takes on the task of protecting tiny creatures living on a dust speck that he has placed on a clover.

At one point in the story, a bird steals the clover from Horton and drops it over a very large clover field at 6:56 a.m. Ever the faithful protector and true to his promise to save them, "Because, after all, a person's a person, no matter how small," Horton begins the enormous task of searching for the lost clover.

But clover, by clover, by clover he found
That the one that he sought for was just not around.
And by noon poor old Horton, more dead than alive,
Had picked, searched, and piled up, nine thousand and five.

1. At this rate, estimate how many clovers Horton picked each minute.
2. Approximately how many seconds did Horton spend on each clover?

For each of the above answers, round to the nearest whole unit.

The story continues

Then, on through the afternoon, hour after hour...
Till he found them at last! On the three millionth flower!

You need only choose one of these questions to answer:

A. If Horton continued at the rate you calculated above without pausing, how long would it take him to reach the three millionth flower? Be sure to answer this question in a way that makes sense (in other words, don't give an answer like 72 hours when 3 days would give us a better sense of how long this is).

 or

B. In the story it seems that Horton finds the clover later the same day. If he continued picking from noon until he found the clover at six o'clock that same evening, approximately how fast would he have to work?

This weeks POW is fun,
Comprehensive answers will be done,
Incomplete answers are not fine,
Nor is just having the "answer" in mind,
Working in partners will do
But don't post until your answer is true. :-)

 Dr. Suesseckman

Solution:
1. At this rate, estimate how many clovers Horton picked each minute.
a. 30 clovers per minute


2. Approximately how many seconds did Horton spend on each clover?
a. 2 seconds per clover.


You need only choose one of these questions to answer:


a. If Horton continued at the rate you calculated above without pausing, how long would it take him to reach the three millionth flower? Be sure to answer this question in a way that makes sense (in other words, don't give an answer like 72 hours when 3 days would give us a better sense of how long this is).
a. It would take Horton about 10 weeks of non-stop picking to get 3 million clovers.


or


b. In the story it seems that Horton finds the clover later the same day. If he continued picking from noon until he found the clover at six o'clock that same evening, approximately how fast would he have to work?
a. 8,308 clovers per minute to finish by 6:00 pm.

Moneybags

While the snow was lightly falling on the ground outside Grandfather Pennywise's large mansion, he called to all his grandchildren to gather round the big easy chair in his den. Excitement was in the air, because they knew what was coming. The grand tradition was about to be enacted for another year. Dear old rich Grandfather "Moneybags" (as the children lovingly called him) always gave them money at Yuletide.

Grandfather always did so in an unusual, unique way, he gave to each of his grandsons as many dollars as there were grandsons, and to each of his granddaughters as many dollars as there were granddaughters.

After the envelopes containing each child's portion had been handed out, Linda exclaimed, "Grandad, you've given out $841 this year! Thank you!"

Of course, every grandchild (except the newborns) rushed to their grandfather to give him a hug and wish him a very Happy Holiday.


How many hugs did the kind old gentleman receive?


Good Luck Ms. L.

Here is the solution for this problem.


This problem was connected to our work with the Pythagorean theorem. The first solution was:



s^2 + d^2 = 841


where s = the number of grandsons (the dollars each boy would receive),
and d = the number of granddaughters (the dollars each girl would receive).


B² + G² = 29²

That is just a simple A² + B² = C².  20 and 21. Now, we know that there are more girls than boys, so G = 21 and B = 20.  Since there are 41 kids, the grandfather would receive 41 hugs if he got one from each grandchild, but the problem states that the newborn twins did not give him a hug, so he only received 39 hugs.

Thanksgiving Time

A large Thanksgiving banquet served between 500 and 600 people. The dinner rolls came in baker's dozens (packages of 13). After everyone had been served a roll there were a number of empty packages plus one open package with 10 rolls left. The pies for dessert had each been cut into ninths, and after everyone had been served a slice there were a number of empty pie tins plus one pie tin with 4 slices left. The tables in the banquet hall each had room for 15 guests. All but one of the tables were full. How many people were seated at that last table?

Be sure to completely explain your method and your answer.  Each step you used should  be explain.  Anyone who does not understand math should be able to follow your process and get the same answer.

Have fun and good luck,
Ms. L.

The Three Candy Corn Jars

In my favorite shopping mall downtown there is a specialty shop that's bound to please anybody's sweet tooth. It's a candy store called Candylandia.In this store you can find just about any kind of candy your tastebuds would savor.

One favorite and traditional candy is the candy corn. Candylandia sells candy corn in three different-sized jars: small, medium, and large. The owner, who loves fairy tales too, calls them the Baby Bean jar, the Mama Bean jar, and the Papa Bean jar, respectively.


Strange as it may seem, each jar of a given size always contains the same number of candy corn as any other jar of that size.


One day, Mrs. Goldie Lochs brought her 9-year-old set of triplets, who had a big craving for candy corn, into the store. Each child (Allen, Bradley, and Charles) bought two different jars of candy corns, but none of the combinations were the same. At home, the children decided to count the number of corns that they had purchased.

Allen announced, avidly, "I have 157 candy corns!"
Bradley boasted boldly, "But I have 47 more than you do, so there!"

Charles chimed in, calmly, "Well, I have 112 less than you two guys have together, but I'm not complaining."


Using this unusual collection of information, please tell me how many candy corns are placed in each jar. Be careful to properly identify any variables you use. State your equations and describe in words how you solved the problem. Then give your equations and work them out for us.

Good Luck,
Ms. L.

P.S. Happy Birthday Mohandas Karamchand Gandhi


Solution:

What I noticed this week was many people did not read the problem carefully.  It stated that each child bought two (2) jars each.  You needed to give the size of the two jars and the total amount of candy.  You all gave me the total but not the size of the jars.  I also noticed many of you posted as partners.  If you do not see your posting please come and see me.
Ms. L.


Allen has 157 candy corns with the combination of a small jar and a
medium jar. A small jar contains 56 candy corns, and a medium jar
contains 101.

 56 + 101 + 157

 Brad has 204 candy corns with the combination of a small jar and a
large jar. A small jar contains 56 candy corns, and a large jar
contains 148.

 56 + 148 = 204

 Charles has 249 candy corns with the combination of a medium jar and
a large jar. A medium jar contains 101 candy corns, and a large jar
contains 148.


101 + 148 = 249

Math Club Party

After looking at the submissions today I can tell you no one has the correct answer yet.  SD and MC are very, very close!  Keep going and see how you do!  We will work on it again next Friday.

Ms. L.

The Math Club is having a party. Members of the club bring presents to give to the other members of the club. Every club member brings the same number of gifts to the party. If the presents are opened in 5 minute intervals starting at 1:00pm the last gift will be opened starting at 5:35pm.

• How many club members are there?

Solution:

Many of you were fabulous about including your thinking.  Don't forget to show what you consider your proof for your solution.  Refer back to the 8th grade page for the writing requirement.



Your final answer should have been 8 people present and 56 gifts. If there were 2 club members each would bring one present and the second present would be opened starting at 1:05. If there were 3 club members each would bring a present for the others in the club meaning 2 presents. You can see a summary in the chart. In the true sense of holiday giving each club member gave a gift to every club member. Of course, they did not give a gift to themselves.
