Q: Lisa is looking to attempt a World Record. She has decided to try and match Joey Chestnut's record of eating 75 full hotdogs, buns included, in 10 minutes. Halfway through the time Lisa has eaten 20 hotdogs. How many hotdogs will she have to eat per minute to at least tie Joey Chestnut's record?
A: Joey Chestnut ate 75 hotdogs to claim the record and Lisa has eaten 20 hot dogs so far, so she still needs to eat 75 - 20 = 55 hotdogs to tie Joey Chestnut. Lisa has a 10 minute time period to eat the hotdogs and half the time has already passed, which means Lisa has 10 / 2 = 5 minutes left until the competition is over. If she needs to eat 55 hotdogs to tie Joey Chestnut and there are 5 minutes left in the competition period then she needs to eat 55 / 5 = 11 hot dogs per minute to have a chance of tying for a win. The answer is 11.
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.

Question: John sublets his apartment to 3 people who each pay $400 per month. He rents the apartment for $900 a month. How much profit does he make in a year?
Answer: He gets 3 * $400 = $1200 per month. So he gets 1200 * 12 = $14,400 per year. So he pays 12 * 900 = $10800 a year. That means his profit is 14400 - 10800 = $3600 per year. The answer is 3600.
