### Who Has What...\$

Team up with someone from another Maths group and work your way through the following problem. Remember, your thinking and strategies are more important than your answer.

1. Me&Porscha,

Think that the answer is \$15.75.

Because, We started off with \$1.50, then multiplied it by 7 which equalled \$10.50, next we halved that which was \$5.25, lastly we multiplied it by 3, which all added up to 15.75

1. I like how you started at the end of the problem and worked on from there. Can you tell me what you added together to get 15.75?

2. Jaylee, Hueloata and I think that the answer is \$33 dollars because

First we times billy's money (\$1.50) by 7 to see how much Lucy has and came up with the answer \$10.50. So then we halved \$10.50 to make Tom's money which is \$5.25. Then after that we times \$5.25 by 3 and came up with the answer \$15.75. Then we added all the money together and came up with the answer \$33.

1. Great explanation for the first part of the question. Could you please tell me more about the strategies you used for your final calculations?

3. Sam, Xavier and I think that the answer is \$ 37.50 dollars because,

We know that Billy has \$1.50 and it says to times Billy's money by seven to see how much money Lucy has in total. So Sam, Xavier and I came up with the answer that, \$1.50 times 7 is 12.50. Then it says that Tom has half of what Lucy has. Like I said before the total money Lucy has is \$12.50 so half of \$12.50 is \$6.50 and \$6.50 is what Tom has in total.

Serena and Alexandria

We thought that we should start by using timetables. First we timed \$ 1.50 and 7 to find out how much money lucy has.Which is \$ 10.50.Then we halfed 10.50 to see how much money tom has, which is \$ 5.50. Then we timed \$ 5.50 with 3 because Maddie has 3 times as much as tom.Also Maddie has \$ 16.50 Then we had to add it all up.And the total all up is \$32.50.

1. Nice effort girls! \$5.50 X 3 = \$16.50, but are you able to explain how half of \$10.50 is \$5.50?

2. Alexandria's reply on this comment

Because half of \$10 is \$5.So we thought that it was 5.50, now that I see it I was wrong it's 5.25.Because half of 50c. Which is 25c.

5. Mateo,Tana,Niuma,and I think that we should start by times table so \$1.50 times 7 equals \$10.50 some that means maddie has got \$30.00

1. Tell me more about Maddie and her \$30? How much did they have altogether?

6. Taeshell, Faaao, CheyanneApril 12, 2013 at 2:51 PM

Cheyanne, Faaao and I think that the answer is \$33.00. First we multiplied \$1.50 by 7, and that was \$10.50. Next we halved \$10.50 which equaled \$5.25. Then we timed it by 3 which equalled \$15.75. After we added it all up and it came to a total of \$33.00.

1. Some of your classmates think the total should be \$32.50. Tell me more about your calculations. Nice group effort!

7. Jacob and I think \$1.50 times 7 will be 10.50.So that means has got about \$30 left.

1. Nice beginning guys, and it looks like you tried to estimate an answer. Tell me more about your thinking that helped you arrive at \$30. Do we need to know how much he has left?

8. Alexandria

I think that the answer is \$33.75c
