[Question]Andrew's father buys a package of 100 masks. Andrew lives with his 2 parents and 2 siblings. All members of Andrew's family change masks every 4 days. How many days will it take to finish the pack of masks?
[Answer]Andrew's family consists of 1 + 2 + 2 = 5 people. Each of Andrew's family members uses 100 masks / 5 = 20 masks. With everyone wearing a mask every 4 days, the masks will last 20 masks * 4 days / mask = 80 days. The answer is 80.
Q: After 100 new people move into a town, 400 of the original population move out. Every year afterward, the town's population is halved. After 4 years, the population is 60 people. Before the new people moved in, how many people lived in the town?
A: If the population is halving then at the end of the third year, the population must have been 60 people in the fourth year * 2 = 120 people. In the second year, the population was 120 people in the third year * 2 = 240 people. And in the first year, the population was 240 people in the third year * 2 = 480 people. Additional people moved out in the first year, so accounting for these shows the population was 480 people + 400 people who moved out = 880 people. Then removing the new people shows there were originally 880 people 100 new people = 780 people. The answer is 780.

[Question]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?
[Answer]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.
