[Question]In a race, there are eight runners. The first five runners finish the race in 8 hours, while the rest of the runners finish the race 2 hours later. Calculate the total time the eight runners took to finish the race.
[Answer]The first five runners took a combined total of 5 * 8 = 40 hours to finish the race. The number of runners who finished the race 2 hours later after the first five is 8 - 5 = 3. The 3 runners who finished the race 2 hours later took a total of 8 + 2 = 10 hours to run the race. Together, the three runners who finished the race in 10 hours took a total of 10 * 3 = 30 hours. All eight runners took 30 + 40 = 70 hours altogether to finish the race. The answer is 70.
Q: John buys 1.5 ounces of silver and twice as much gold. The silver costs $20 per ounce. The gold is 50 times more expensive per ounce. How much does he spend on everything?
A: He buys the silver for 1.5 * $20 = $30. He bought 1.5 * 2 = 3 ounces of gold. The gold is worth %20 * 50 = $1000 per ounce. So he buys 3 * $1000 = $3000 on gold. So he spent $30 + $3000 = $3030 on everything. The answer is 3030.

[Question]On Friday, Remy paid Sally’s Woodworking LLC a total of $20,700 for 150 pieces of furniture. Later that evening, the company’s accountant discovered that a new intern in the sales department had overcharged Remy. If the cost of a piece of furniture is $134, how much money will Sally’s Woodworking LLC reimburse Remy?
[Answer]The total cost of all the pieces of furniture should be 134 * 150 = 20100 dollars. Sally’s Woodworking LLC will reimburse Remy the difference between the total cost and the amount he paid, which is 20700 - 20100 = 600 dollars. The answer is 600.
Q: Jason has six fish in his aquarium. He realizes that every day the number of fish doubles. On the third day he takes out one-third of the fish. On the fifth day he takes out one-fourth of the fish. On the seventh day he adds 15 more fish. How many fish in total does he have?
A: Start by finding how many fish were in the aquarium on the third day 6 * 2 * 2 = 24. On day three, Jason took out one - third of the fish 24 / 3 = 8. So at the end of day three, he has 24 - 8 = 16 fish. On day five he has 16 * 2 * 2 = 64 fish, but he takes out one - fourth. So he took out 64 / 4 = 16 fishes. So at the end of day five, he has 64 - 16 = 48 fish. On day seven he has 48 * 2 * 2 = 192 fish. He adds in 15 more, so he has 192 + 15 = 207 fish in total. The answer is 207.
