Q: James decides to replace his car. He sold his $20,000 car for 80% of its value and then was able to haggle to buy a $30,000 sticker price car for 90% of its value. How much was he out of pocket?
A: He sold his car for 20000 * .8 = $16,000. He bought the new car for 30,000 * .9 = $27,000. That means he was out of pocket 27,000 - 16,000 = $11,000. The answer is 11000.
Question: Janet filmed a new movie that is 60% longer than her previous 2-hour long movie. Her previous movie cost $50 per minute to film, and the newest movie cost twice as much per minute to film as the previous movie. What was the total amount of money required to film Janet's entire newest film?
Answer: The first movie was 2 * 60 = 120 minutes. So this movie is 120 * .6 = 72 minutes longer. So this movie is 192 minutes. It also cost 50 * 2 = $100 per minute to film. So it cost 192 * 100 = $1920. The answer is 1920.
[Question]Marcy's grade is electing their class president. Marcy got three times as many votes as Barry, who got twice as many as 3 more than the number of votes Joey got. If Joey got 8 votes, how many votes did Marcy get?
[Answer]First, add three to Joey's vote total: 8 votes + 3 votes = 11 votes. Then double that number to find the number of votes Barry got: 11 votes * 2 = 22 votes. Then triple that number to find Marcy's vote total: 22 votes * 3 = 66 votes. The answer is 66.
Q: Ariella has $200 more in her son's saving account than Daniella has in her son's savings account. Ariella's account earns her simple interest at the rate of 10% per annum. If Daniella has $400, how much money will Arialla have after two years?
A: If Ariella has $200 more in her son's saving account than Daniella has, then she has $400 + $200 = $600. If she earns an interest of 10% in the first year, her savings account increases by 10 / 100 * $600 = $60. In the second year, she earns the same amount of interest, which $60 + $60 = $120. The total amount of money in Ariella's account after two years is $600 + $120 = $720. The answer is 720.

Saly saves 1 / 2 * $6 / day = $3 / day. Since each year have 365 days, the total amount of money Sally will save in a year is $3 / day * 365 days / year = $1095 / year. Bob saves 1 / 2 * $4 / day = $2 / day. The total amount of money Bob will have saved in a year is $2 / day * 365 days / year = $730 / year. In total, Sally and Bob would have saved $730 + $1095 = $1825. The answer is 1825.
