[Question]: Rose is an aspiring artist. She wants a paintbrush that costs $2.40, a set of paints that costs $9.20, and an easel that costs $6.50 so she can do some paintings. Rose already has $7.10. How much more money does Rose need?
[Answer]: The total cost of the paintbrush, the paints, and the easel was $2.40 + $9.20 + $6.50 = $18.10. Rose needs $18.10 - $7.10 = $11 more.
So the answer is 11.

[Question]: The local school is holding a big fair to raise money for 5 classes that want to go on a trip. 150 people came to the party and paid a total of $368 for entrance tickets. There was a raffle which brought in $343. The sale of cakes and drinks brought $279. At the end of the fair, the principal of the school shared the money raised between the 5 classes. How much money did each class receive?
[Answer]: First, let’s calculate the total amount of money collected, which is 368 + 343 + 279 = $990. Let us now share this sum between the 5 classes: 990 / 5 = $198.
So the answer is 198.

[Question]: John decides to buy some birds. He got 50 dollars from each of his 4 grandparents. If each bird costs $20, how many wings did all the birds have?
[Answer]:
He got 4 * 50 = $200. That means he was able to buy 200 / 20 = 10 birds. Since each bird has 2 wings he got 10 * 2 = 20 wings.
So the answer is 20.
