Question: Brian goes fishing twice as often as Chris, but catches 2/5 times fewer fish than Chris per trip. If Brian caught 400 fish every time he went fishing, how many fish did they catch altogether if Chris went fishing 10 times?
Answer: If Brian caught 400 fish in one trip, he caught 2 * 400 = 800 fish in two trips. Since Brian catches 2 / 5 times less fish than Chris per trip, Chris catches 2 / 5 * 400 = 160 more fish in one fishing trip. Chris's total number of fish in one trip is 400 + 160 = 560 fish. In 10 trips, Chris catches 560 * 10 = 5600 fish. If in his two trips Brian catches 800 fish, and he goes fishing twice as often as Chris, if Chris goes fishing 10 times, Brian will catch 800 * 10 = 8000 fish. The total number of fish they'll catch if Chris goes fishing ten times is 8000 + 5600 = 13600. The answer is 13600.
[Question]In a factory, there are 3 machines working 23 hours a day. The owner decided to buy a fourth machine, which works only 12 hours a day. One machine can produce 2 kg of material every hour. The factory sells the produced material for $50 per 1 kg. How much can this factory earn in one day?
[Answer]The total runtime for the first three machines is 3 machines * 23 hours / day / machine = 69 hours / day. So these machines could produce 69 hours / day * 2 kg / hour = 138 kg / day. The fourth machine could produce 12 hours / day * 2 kg / hour = 24 kg / day of material. In total all the machines would produce 138 kg / day + 24 kg / day = 162 kg / day of material. The factory would therefore earn 162 kg / day * $50 / kg = $8100 / day. The answer is 8100.
Q: Mark hires a singer for 3 hours at $15 an hour. He then tips the singer 20%. How much did he pay?

Question: It will cost $60 to rent a sailboat and $80 per hour to rent a ski boat. Ken rented a sailboat while Aldrich rented a ski boat. How much more did it cost Aldrich to rent the ski boat than Ken to rent a sailboat for three hours a day in two days?
Answer: Ken paid $60 x 3 = $180 to rent a sailboat for 3 hours in a day. Aldrich paid $80 x 3 = $240 to rent a ski boat in 3 hours in a day. So Aldrich paid $240 - $180 = $60 more to rent a ski boat than Ken to rent the sailboat each day. Therefore, it cost Aldrich $60 x 2 = $120 more to rent a ski boat than Ken to rent the sailboat in two days. The answer is 120.
