Q: Jerry is cutting up wood for his wood-burning stove. Each pine tree makes 80 logs, each maple tree makes 60 logs, and each walnut tree makes 100 logs. If Jerry cuts up 8 pine trees, 3 maple trees, and 4 walnut trees, how many logs does he get?
A: First find the total number of pine logs by multiplying the number of trees by the number of logs per tree: 80 logs / pine * 8 pines = 640 logs. Then do the same thing for the maple trees: 60 logs / maple * 3 maples = 180 logs. And do the same thing for the walnut trees: 100 logs / walnut * 4 walnuts = 400 logs. Finally, add up the number of logs from each type of tree to find the total number: 640 logs + 180 logs + 400 logs = 1220 logs. The answer is 1220.

Q: Ben wants to pick 56 sugar snap peas. At his current rate of picking, all will be picked in seven minutes. How long, in minutes, would it take Ben to pick 72 sugar snap peas?
A: In 1 minute, Ben picks 56 / 7 = 8 sugar snap peas. Ben would take 72 / 8 = 9 minutes to pick 72 sugar snap peas. The answer is 9.

Q: John decides to learn how to play the piano. He buys a piano for $500. He then hires a teacher for 20 lessons at $40 per lesson but ends up getting a 25% discount. How much did everything cost?
A:
The normal price of the lessons would be 20 * 40 = $800. The discount saves him 800 * .25 = $200. So the lessons cost him 800 - 200 = $600. That means everything costs 500 + 600 = $1100. The answer is 1100.
