[Question]Janet goes to the gym for 5 hours a week. She goes Monday, Tuesday, Wednesday, and Friday. She spends an hour and a half each day on Monday and Wednesday. If she spends the same amount of time at the gym on Tuesday and Friday how many hours is she at the gym on Friday?
[Answer]Between Monday and Wednesday, she spends 1.5 hours + 1.5 hours = 3 hours. That means she has 5 hours - 3 hours = 2 hours left for Tuesday and Wednesday. She spends 2 hours / 2 = 1 hour on Friday. The answer is 1.
Q: Lilith is trying to break the world record for largest cap collection. She collects 3 caps per month in the first year, and 5 caps per month after the first year. Each Christmas, she also receives 40 caps from friends and family. She estimates that each year, she loses 15 of the caps she has collected. If Lilith has been collecting for 5 years, how many caps has she collected so far?
A: In the first year, Lilith collects 3 caps * 12 months = 36 caps. Every year afterwards, she collects 5 caps * 12 months = 60 caps. She does this for a total of 5 1 = 4 years. This is a total of 60 caps * 4 years = 240 caps. In total, she collects 36 + 240 = 276 caps by herself. Over the Christmases, she receives 40 caps * 5 years = 200 caps from friends and family. She also loses 15 caps * 5 years = 75 caps over the years. She has therefore collected 276 + 200 75 = 401 caps. The answer is 401.

Question: Mason is cleaning out all the junk in his attic. 20% of the items are useful, 10% are valuable heirlooms, and 70% are junk. If Marcus's attic has 8 useful items in it, how many junk items does it have?
Answer:
First find the total number of items in the attic by dividing the number of useful items by the percentage of useful items: 8 items / .2 = 40 items. Then multiply the total number of items by the percentage that are junk to find the number of junk items: 40 items * .7 = 28 items. The answer is 28.
