[Question]Joseph invested $1000 into a hedge fund. The fund promised a yearly interest rate of 10%. If he deposited an additional $100 every month into the account to add to his initial investment of $1000, how much money will he have in the fund after two years?
[Answer]For the first year, Joseph will have invested $1000 + ($100 * 12) = $2200. The interest calculated for the first year will be $2200 * 10% = $220. The total value of the investment for the first year will be $2200 + $220 = $2420. For the second year, the total invested will be $2420 + ($100 * 12) = $3620. The interest calculated after the second year will be $3620 * 10% = $362. Therefore, Joseph's investment in the mutual fund will be worth $3620 + $362 = $3982. The answer is 3982.

Question: A hot air balloon with 200 balloons is blowing up. After about half an hour, 1/5 of the total number of balloons in the hot air balloon have blown up. After another hour, twice the number of balloons that had already blown up also blow up. How many balloons in the hot air balloon remain intact?
Answer: After half an hour, the number of balloons that had blown up is 1 / 5 * 200 = 40. The number of balloons that haven't blown up so far is 200 - 40 = 160. In the next hour, 2 * 40 = 80 balloons blow up. The number of balloons that haven't blown up now is 160 - 80 = 80. The answer is 80.
[Question]Tropical Storm Sally brings 3 days of rain to southern Texas. The first day it rained 4 inches. The second day it rained 5 times as much as the first day, and the third day it rained 6 inches less than the sum of the first two days. How much did it rain on the third day?
[Answer]First Day:4 inches. Second Day: 5(4) = 20 inches. Third Day: (4 + 20) - 6 = 18 inches. The answer is 18.
[Question]Jerry is trying to cut down on the amount of soda he drinks. Right now, he drinks 48 sodas a week. If he cuts the number of sodas he drinks in half each week, how many weeks will it take him to only drink 6 sodas per week?
[Answer]
Figure out how many sodas Jerry drinks after 1 week by dividing the starting number of sodas by 2: 48 sodas / 2 = 24 sodas. Now repeat the process to figure out how many soda he drinks after 2 weeks: 24 sodas / 2 = 12 sodas. Repeat the process one more time to find the number of sodas after 3 weeks: 12 sodas / 2 = 6 sodas. It takes Jerry 3 weeks to get down to 6 sodas. The answer is 3.
