[Question]Osborn is testing a new way to get dressed in the morning on school days so he goes faster and can get up later. He tracks his time for the week and on Monday is takes him 2 minutes. On Tuesday it takes him 4 minutes. On Wednesday it takes him 3 minutes. On Thursday it takes him 4 minutes. Before Friday arrives he looks at his old way of getting dressed and sees that it was taking him 3 minutes on average to get dressed. How fast does he have to get dressed on Friday so his weekly average ties his old method?
[Answer]If it takes on average 3 minutes to get dressed, then it takes 15 minutes total on the school week because 5 x 3 = 15. Thus far this week it has taken him 13 minutes to get dressed because 2 + 4 + 3 + 4 = 13. To tie his previous method, he needs to take 2 minutes on Friday because 15 - 13 = 2. The answer is 2.
Q: On Blacks, Martha goes to the mall to buy clothes on sale. For every 2 jackets she buys, she gets 1 free jacket. For every 3 t-shirts she buys, she gets 1 free t-shirt. Martha decides to buy 4 jackets and 9 t-shirts. How many clothes will she take home?
A: For buying 4 jackets Martha gets 4 jackets / 2 = 2 jackets for free. For buying 9 t - shirts, Martha gets 9 t - shirts / 3 = 3 t - shirts for free. Adding the free jackets, Martha gets 4 jackets + 2 jackets = 6 jackets. Adding the free t - shirts, Martha gets 9 t - shirts + 3 t - shirts = 12 t - shirts. In total, Martha will take home 6 jackets + 12 t - shirts = 18 clothes. The answer is 18.

[Question]Penelope has 5 M&M candies for every 3 Starbursts candies. If she has 25 M&M candies, how many Starbursts candies does she have?
[Answer]Let 5 M&M candies and 3 Starbursts candies be referred to as the unit amounts of each candy. 5 M&M candies make one unit so 25 makes 25 / 5 = 5 units of M&M candies.

The answer is 15.
Q: Davonte is trying to figure out how much space his art collection takes up. He measures his paintings and finds he has three square 6-foot by 6-foot paintings, four small 2-foot by 3-foot paintings, and one large 10-foot by 15-foot painting. How many square feet does his collection take up?
A: His square paintings take up 36 square feet each because 6 x 6 = 36. His small paintings take 6 square feet each because 2 x 3 = 6. His large painting takes up 150 square feet because 10 x 15 = 150. Combined, his square paintings take up 108 square feet because 3 x 36 = 108. Combined, his small paintings take up 24 square feet because 4 x 6 = 24. In total, his paintings take up 282 square feet because 150 + 108 + 24 = 282. The answer is 282.
