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.

Q: Carlson bought land that cost $8000 and additional land that cost $4000. He initially owned 300 square meters of land. If the land he bought costs $20 per square meter, how big is his land after buying the new land?
A: Carlson bought land that cost $20 per square meter, therefore the size of the land he bought is 8000 / 20 = 400. And the size of the other land he bought is 4000 / 20 = 200. Therefore the total size of the land he owns is 400 + 200 + 300 = 900. The answer is 900.
Question: On Saturday morning, Renata had $10 to spend. She first went and made a $4 donation in exchange for a ticket to the local charity draw. When the draw was done, she was declared the winner of the 5th prize of $90. Excited, she quickly dashed to play slots at one of the casinos in Atlantic City. Unfortunately, she lost $50 at the first slot machine, $10 at the second and $5 at the last one. Dejected, she decided to take a long walk. She soon grew thirsty and entered the first gas station she saw. She picked a $1 bottle of water and while paying for it, she bought a $1 lottery ticket. To her utter delight, she won an instant prize of $65. How much money did Renata end up having?
Answer:
After the charity ticket purchase on Saturday morning, Renata remained with 10 - 4 = 6 dollars. Adding the prize money give her 6 + 90 = 96 dollars. At the casino, she lost 50 + 10 + 5 = 65 dollars. Thus far, Renata remained with 96 - 65 = 31 dollars. The amount she spent on the bottle of water and lottery ticket is 1 + 1 = 2 dollars. This means that she remained with 31 - 2 = 29 dollars. Since she won 65 dollars, Renata’s ended up having 29 + 65 = 94 dollars. The answer is 94.
