[Question]: Five friends eat at a fast-food chain and order the following: 5 pieces of hamburger that cost $3 each; 4 sets of French fries that cost $1.20; 5 cups of soda that cost $0.5 each; and 1 platter of spaghetti that cost $2.7. How much will each of them pay if they will split the bill equally?
[Answer]: The cost of 5 pieces of hamburger is $3 x 5 = $15. The cost of 4 sets of French fries is $1.20 x 4 = $4.80. The cost of 5 cups of soda is $0.5 x 5 = $2.50. So their total bill is $15 + $4.80 + $2.50 + $2.7 = $25. Hence, each of the five friends will contribute $25 / 5 = $5.
So the answer is 5.

[Question]: Jack is trying to stack cans in his emergency bunker. If he can fit 12 cans in one row, 4 rows on one shelf, and 10 shelves in one closet, how many cans can he store in each closet?
[Answer]: First find the total number of cans Jack can fit on one shelf: 12 cans / row * 4 rows / shelf = 48 cans / shelf. Then find the number of cans he can fit on all the shelves in one closet: 48 cans / shelf * 10 shelves = 480 cans.
So the answer is 480.

[Question]: 10 boxes each contain 50 bottles of water. Each bottle has a capacity of 12 liters and is filled up to 3/4 of its capacity. How many liters of water altogether are contained within the bottles in the boxes?
[Answer]:
Since each water bottle has a capacity of 12 liters, when filled up to 3 / 4 of capacity, each carries 3 / 4 * 12 = 9 liters of water. If there are 50 bottles of water in each box, the number of liters the water bottles in a box are carrying is 50 * 9 = 450 liters. In 10 boxes containing bottled water, the total number of liters in the water bottles is 450 * 10 = 4500 liters.
So the answer is 4500.
