[Question]There are three machines in a factory. Machine A can put caps on 12 bottles in 1 minute. Machine B can put caps to 2 fewer bottles than Machine A. Machine C can put caps to 5 more bottles than Machine B. How many bottles can those three machines put caps on in 10 minutes?
[Answer]Machine A can put caps on 12 x 10 = 120 bottles in 10 minutes. Machine B can put caps on 12 - 2 = 10 bottles in 1 minute. So in 10 minutes, machine B can put caps on 10 x 10 = 100 bottles. Machine c can put caps on 10 + 5 = 15 bottles in 1 minute. So in 10 minutes, machine C can put caps on 15 x 10 = 150 bottles. Therefore, the three machines can put caps on 120 + 100 + 150 = 370 bottles in 10 minutes. The answer is 370.
Q: John's weight bench can support 1000 pounds. He wants to make sure to stay 20% under that weight for safety. If he weighs 250 pounds how much weight can he put on the bar?
A: He wants to stay 1000 * .2 = 200 pounds under the max. So he wants to stay under 1000 - 200 = 800 pounds. That means he can put 800 - 250 = 550 pounds on the bar. The answer is 550.
Question: Janet likes collecting action figures in her spare time. She currently owns 10 action figures and sells 6 of them to get 4 that are in better condition. Her brother then gives her his collection which is twice the size of what Janet has at the time. How many action figures does she now have in total?
Answer: Janet has 10 action figures and sells 6 so she has 10 - 6 = 4 action figures left. She then buys four more so she now has 4 + 4 = 8 action figures. Her brother gives her his collection which is 2 * 8 = 16 action figures. Now in total, she has 8 + 16 = 24 action figures. The answer is 24.

Question: Flies are Betty's frog's favorite food. Every day the frog eats 2 flies. Betty puts the flies she finds in a bottle. In the morning Betty catches 5 flies inside a bottle, and in the afternoon she catches 6 more, but when she removes the lid, one escapes. Betty wants to gather the whole week's food for her frog. How many more flies does she need?
Answer:
The frog eats 2 flies / day * 7 days / week = 14 flies a week. Betty catches flies in the morning and in the afternoon, for a total of 5 flies + 6 flies = 11 flies. But 1 fly escapes, leaving 11 flies - 1 fly = 10 flies. To get her frog's food for the whole week, Betty needs 14 flies - 10 flies = 4 more flies. The answer is 4.
