A: He makes 1.5 - 1 = $.5 from each candy bar. He sells 5 * 10 = 50 candy bars. So he makes 50 * .5 = $25. The answer is 25.
Question: 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?
Answer: 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.
[Question]Wally gives 3/4 of his 400 tickets to his two friends Jensen and Finley, who share the tickets in a ratio of 4:11. How many tickets does Finley get?
[Answer]Wally gives his friends 3 / 4 * 400 = 300 tickets to share. The total ratio that represents the tickets that Jensen and Finley share is 4 + 11 = 15. From the total ratio, the fraction that represents the share that Finley got is 11 / 15, and since he shared with Jensen 300 tickets, he got 11 / 15 * 300 = 220 tickets. The answer is 220.
Q: Lucca bought 200 pieces of bread. Lucca ate 1/4 of the pieces of bread in one day, and 2/5 of the remaining pieces the next day. If he ate half of the remaining pieces on the third day, calculate how many pieces of bread are remaining.
A: On the first day, Lucca ate 1 / 4 * 200 = 50 pieces. The number of pieces remaining after the first day is 200 - 50 = 150. On the second day, Lucca ate 2 / 5 * 150 = 60 pieces of bread. The pieces of bread that remained after the second day is 150 - 60 = 90. If Lucca ate half of the remaining pieces of bread on the third day, he ate 1 / 2 * 90 = 45 pieces. The pieces of bread that are remaining after the third day are 90 - 45 = 45. The answer is 45.
Question: Iris has a berry farm. Her brother and sister help her to pick up the berries and sell them to the market. Iris picked 30 blueberries, her sister picked 20 cranberries, and her brother was able to pick 10 raspberries. If 1/3 of the total berries they were able to pick are rotten and the remaining 1/2 of the fresh berries need to be kept, how many berries will they be able to sell?
Answer: Iris and his brother and sister were able to pick a total of 30 + 20 + 10 = 60 berries. The rotten berries that needed to be thrown away are (1 / 3) x 60 = 20. So, the total number of fresh berries is 60 - 20 = 40. The berries they need to keep are (1 / 2) x 40 = 20. Therefore, the total number of berries they will be able to sell is 40 - 20 = 20. The answer is 20.

John bought 2 notebooks for his 3 children: 2 notebooks / child x 3 children = 6 notebooks. The father bought 6 notebooks. John's wife bought 5 notebooks for their three children: 5 notebooks / child x 3 children = 15 notebooks. The mother bought 15 notebooks. Now, the total number of notebooks is 6 notebooks + 15 notebooks = 21 notebooks. The answer is 21.
