Q: Lavinia’s daughter is 10 years younger than Katie’s daughter. Lavinia’s son is 2 times the age of Katie’s daughter. If Katie’s daughter is 12 years old, how many years older is Lavinia’s son than Lavinia’s daughter?
A: Lavinia’s daughter is 12 - 10 = 2 years old. Lavinia’s son is 12 * 2 = 24 years old. Lavinia’s son is 24 - 2 = 22 years older than Lavinia’s daughter. The answer is 22.
Question: To get admission into a school party, each football team member must pay $40. If there are 60 players on the football team and the entire team attends 8 such parties in a year, calculate the total amount of money collected in the 8 parties.
Answer: In one party, the total amount of money collected from the football players is $40 * 60 = $2400. If eight such parties are done in a year, the total amount of money collected from the parties is $2400 * 8 = $19200. The answer is 19200.
[Question]Bill is making omelets for his family's breakfast. It takes him 3 minutes to chop a pepper, 4 minutes to chop an onion, and 1 minute to grate enough cheese for one omelet. It takes him 5 minutes to assemble and cook the omelet. If he needs to chop up four peppers, two onions, and also grates cheese for cooking each of five omelets, how long will he spend preparing for and cooking the five omelets?
[Answer]First find the total time Bill spends chopping peppers: 4 peppers * 3 minutes / pepper = 12 minutes. Then find the total time Bill spends chopping onions: 2 onions * 4 minutes / onion = 8 minutes. Then find the combined time to grate cheese for and cook each omelet: 5 + 1 minute / omelet = 6 minutes. Then multiply the time per omelet by the number of omelets: 5 omelets * 6 minutes / omelet = 30 minutes. Then add the cook time to the chopping time to find the total time Bill spends: 30 minutes + 12 minutes + 8 minutes = 50 minutes. The answer is 50.

Question: Ned opens a left-handed store. He sells left-handed mice. They cost 30% more than normal mice. He sells 25 a day and his store is open every day except Sunday, Thursday, and Friday. If normal mice cost $120 how much money does he make a week?
Answer: The left - hand mice cost 120 * .3 = $36 more than right - handed ones. So they cost 120 + 36 = $156. So he makes 156 * 25 = $3900 a day. The store is open 7 - 3 = 4 days a week. So in a week, he makes 3900 * 4 = $15,600. The answer is 15600.
Q: Joel is picking peppers from his garden. He picks 7 on Sunday, 12 on Monday, 14 on Tuesday, 12 on Wednesday, 5 on Thursday, 18 on Friday and 12 on Saturday. He knows that in his garden 20% of the peppers are hot and the rest are not. How many non-hot peppers did he pick?
A:
He picked 80 peppers because 7 + 12 + 14 + 12 + 5 + 18 + 12 = 80. 80% of the peppers are not hot because 100 - 20 = 80. He picked 64 non - hot peppers because 80 x .8 = 64. The answer is 64.
