Q: Alex is saving up for a new car. He already has $14,500 saved up and the car costs $14,600. He decides that to make the last of the money he will deliver groceries for people in the neighborhood. He charges $1.5 per trip and then 5% of the price of the groceries. If he makes 40 trips and has saved up enough, how many dollars' worth of groceries did he deliver?
A: He needs to save up $100 because 14,600 - 14,500 = 100. He earned $60 off trips because 40 x 1.5 = 60. He earned $40 off groceries because 100 - 60 = 40. He delivered $800 in groceries because 40 / .05 = 800. The answer is 800.

Question: A soccer team has 24 players. They have scored 150 goals on the season. There have been 15 games played. 1/3 of the players have averaged 1 goal each per game. How many total goals have the other players scored?
Answer: 8 players have averaged 1 goal a game because 24 x (1 / 3) = 8. These players average a total of 8 goals a game because 8 x 1 = 8. These players have scored 120 goals because 8 x 15 = 120. The remaining players have scored 30 total goals because 150 - 120 = 30. The answer is 30.
Q: Nick has 60 cans. Each can takes up 30 square inches of space before being compacted and 20% of that amount after being compacted. How much space do all the cans take up after being compacted?
A:
First find the total amount of space the cans take up before being compacted: 60 cans * 30 sq in / can = 1800 sq in. Then multiply that amount by the percentage of space they take up after being compacted: 1800 sq in * 20% = 360 sq in. The answer is 360.
