[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.
So the answer is 20.

[Question]: It took Alice three months to save up to buy new shoes. If she saved 10 dollars the first month and 30 more each month, how much did she have saved by the end of the third month?
[Answer]: The first month she saved 10 dollars. By the second month, she had 10 + 30 = 40 dollars saved. By the third month, she had 40 + 30 = 70 dollars saved.
So the answer is 70.

[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.
So the answer is 370.
