Q: Tom decides to buy some shirts from his favorite fandoms because there is a sale on his favorite website. He buys 5 t-shirts from each of his 4 favorite fandoms. The shirts normally cost $15 each but there is a 20% off sale. The order qualified for free shipping but he still needed to pay 10% tax. How much did he pay?
A: He bought 5 * 4 = 20 shirts. The discount saves him 15 * .2 = $3 per shirt. So each shirt cost 15 - 3 = $12. So the total order cost 20 * 12 = $240. Tax added 240 * .1 = $24. So he paid 240 + 24 = $264. The answer is 264.
Question: Jane is trying to decide whether to buy a house or a trailer. A house costs $480,000 and a trailer costs $120,000. Each loan will be paid in monthly installments over 20 years. How much more is the monthly payment on the house compared to the trailer?
Answer: First find how many months the loans last: 20 years * 12 months / year = 240 months. Then divide the cost of the house by the number of payments to find the monthly payment before interest: $480,000 / 240 months = $2000 / month. Then do the same thing to find the monthly payment before interest on the trailer: $120,000 / 240 months = $500 / month. Then subtract the cost of the trailer payment from the cost of the house payment to find the difference: $2000 / month - $500 / month = $1500 / month. The answer is 1500.
[Question]Courtney liked to collect marbles. She kept them in mason jars. One jar had 80 marbles. Her second jar had twice that amount. She just started her third jar which currently has 1/4 the amount of her first jar. How many marbles does she have in total?
[Answer]One jar had 80 and the second jar had twice that amount so 2 * 80 = 160 marbles. The third jar had 1 / 4 of the first jar's 80 marbles so it had .25 * 80 = 20 marbles. When you add up all the jars, she had 80 + 160 + 20 = 260 marbles. The answer is 260.

Question: All people named Barry are nice, while only half of the people named Kevin are nice. Three-fourths of people named Julie are nice, while 10% of people named Joe are nice. If a crowd contains 24 people named Barry, 20 people named Kevin, 80 people named Julie, and 50 people named Joe, how many nice people are in the crowd?
Answer: If all people named Barry are nice, and the crowd contains 24 people named Barry, then 1 * 24 = 24 of these people are nice. If only half of people named Kevin are nice, and the crowd contains 20 people named Kevin, then 0.5 * 20 = 10 of these people are nice. If three - fourths of people named Julie are nice, and the crowd contains 80 people named Julie, then (3 / 4) * 80 = 60 of these people are nice. If 10% of people named Joe are nice, and the crowd contains 50 people named Joe, then 0.1 * 50 = 5 of these people are nice. In total, the crowd contains 24 + 10 + 60 + 5 = 99 people who are nice. The answer is 99.
Q: Mikaela earns $10 an hour tutoring. For the first month, she tutored for 35 hours and in the second month, she tutored 5 hours more than the first month. She spent 4/5 of her total earnings on her personal needs and saved the rest of the money. How much did she save?
A:
Mikaela spent 35 + 5 = 40 hours in the second month. So, she tutored a total of 35 + 40 = 75 hours for the first two months. Thus, her total earning was 75 x $10 = $750. And, her total expenses was 4 / 5 x $750 = $600. Therefore, she saved an amount of $750 - $600 = $150. The answer is 150.
