Q: Martin owns a farm with hens. 10 hens do lay 80 eggs in 10 days. Martin decided to buy 15 more hens. How many eggs will all hens lay in 15 days?
A: If 10 hens lay 80 eggs, then 1 hen lays 80 / 10 = 8 eggs in 10 days. That means one hen is laying 8 / 2 = 4 eggs in 5 days. So in 15 days, 1 hen will lay 3 times more eggs, so 4 * 3 = 12 eggs. All hens in total will then lay 25 * 12 = 300 eggs in 15 days. The answer is 300.
Question: For every 1 minute that Carlotta sings on stage during the final opera performance, she spends an additional 3 minutes practicing and 5 minutes throwing temper tantrums. If her final stage performance is 6 minutes long, what is the total combined amount of time, in minutes, that she spends practicing, throwing tantrums, and singing in the final stage performance?
Answer: For each 6 minutes she performs, Carlotta spends 6 * 3 minutes = 18 minutes practicing. For each 6 minutes she performs, Carlotta throws tantrums for 6 * 5 minutes = 30 minutes. Thus, in total, for each 6 minutes of performance time, she spends 18 minutes + 30 minutes + 6 minutes = 54 minutes on all three activities. The answer is 54.
[Question]Louie obtained 80% on a math quiz. He had 5 mistakes. How many items were there on the math quiz?
[Answer]Louie got 100% - 80% = 20% of the total items incorrect, which is equal to 5 items. So 1% is equal to 5 / 20 = 1 / 4 of an item. Hence, the total number of items, represented by 100%, on the math quiz was 1 / 4 of an item x 100 = 25. The answer is 25.

Q: Jackson’s mom packs him a peanut butter and jelly sandwich for his school lunch on Wednesdays and Fridays. There are 36 weeks of school and Jackson has only missed 1 Wednesday and 2 Fridays. How many peanut butter and jelly sandwiches did he eat for lunch this school year?

36 weeks of school x 2 days of the week = 72 days of school. 1 Wednesday + 2 Fridays = 3 days of school missed. 72 days of school – 3 days of school missed = 69 peanut butter and jelly sandwiches eaten. The answer is 69.
