Carson is refilling his tires. Each tire can hold 500 cubic inches of air. Two of the tires are completely flat and empty. One tire is 40% full and the last tire is 70% full. If Carson injects 50 cubic inches of air with each pump, how many pumps will it take him to fill all the tires?
Let's think: First, if the a full tire needs 500 cubic inches of air, then two empty tires need: 500 cubic inches / tire * 2 tires = 1000 cubic inches. Accordingly, the 40% - full tire needs 500 cubic inches * (100% - 40%). So, we find the 40% - full tire needs 500 cubic inches * (60%) = 300 cubic inches. And, the 70% - full tire needs 500 cubic inches * (100% - 70%). So, the 70% - full tire needs 500 cubic inches * (30%) = 150 cubic inches. Now add up the needs of all the tires to find the total number of cubic inches needed: 1000 cubic inches + 300 cubic inches + 150 cubic inches = 1450 cubic inches. Finally, if the pumps each hold 50 cubic inches, the total number of pumps needed is 1550 cubic inches / 50 cubic inches / pump = 29 pumps.. The answer is: 29.

Tamara is 3 times Kim's height less 4 inches. Tamara and Kim have a combined height of 92 inches. How many inches tall is Tamara?
Let's think: Let K = Kim's height. Tamara = 3K - 4. K + 3K - 4 = 92. 4K - 4 = 92. 4K = 96. Kim = 24 inches. Tamara = (3 * 24) - 4 = 68 inches. Tamara is 68 inches tall.. The answer is: 68.

James buys 10 boxes of Capri-sun. Each box has 6 pouches in it. If he paid $12 how many cents does each pouch cost?
Let's think: He bought 10 * 6 = 60 pouches. It cost 12 * 100 = 1200 cents. So each pouch cost 1200 / 60 = 20 cents.. The answer is: 20.

Tommy ordered a total weight of 10 kilograms of apple, orange, grape, and strawberry fruits. He ordered 3 kilograms of apples, 1 kilogram of orange, and 3 kilograms of grapes. How many kilograms of strawberries did he order?
Let's think:
Tommy ordered 3 + 3 + 1 = 7 kilograms of apples, oranges and grapes altogether. Therefore, Tommy ordered 10 - 7 = 3 kilograms of strawberries.. The answer is: 3.
