Sam is stocking up on canned tuna. He got 9 cans at the supermarket, and had 5 coupons for 25 cents off a single can per coupon. He paid $20 and got $5.50 in change. How many cents does a can of tuna cost?
Let's think: His total without the coupons was $20 - $5.50 = $14.50. He had 5 coupons that each saved him 25 cents, so the full price of all the tuna is $14.50 + 5 * $0.25 = $15.75. He bought 9 cans of tuna, so each can costs $15.75 / 9 = $1.75. As 1 dollar has 100 cents 1.75 * 100 = 175 cents.. The answer is: 175.

A train takes 4 hours to reach a destination at a speed of 50 miles per hour. How long would it take if it traveled at 100 miles per hour instead?
Let's think: The distance to the destination is 4 hours * 50 miles / hour = 200 miles. Traveling at 100 miles per hour, it will take 200 miles / (100 miles / hour) = 2 hours.. The answer is: 2.

Melanie does her weekly shopping at the farmer's market. She starts with an 8-ounce wheel of brie cheese. Next is a 1 pound loaf of bread. She grabs a pound of tomatoes and 2 pounds of zucchini. After that, she grabs 1 1/2 pounds of chicken breasts and treats herself to 8 ounces of fresh raspberries and 8 ounces of fresh blueberries. How many pounds of food does she buy?
Let's think:
She bought 8ounces of cheese, 8 - ounce raspberries, 8 ounces of blueberries for a total of 8 * 3 = 24 ounces. 16 ounces are in 1 pound and she has 24 ounces of food so she has 24 / 16 = 1.5 pounds of food. Those items are 1.5 pounds and she bought 1 pound of bread, 1 pound of tomatoes, 2 pounds of zucchini and 1.5 pounds of chicken for a total of 1.5 + 1 + 1 + 2 + 1.5 = 7 pounds of food.. The answer is: 7.
