Q: Tom opens an amusement park. It cost $100,000 to open initially. It also cost 1% of that to run per day. He sells 150 tickets a day for $10 each. How long will it take to make back his money?
A: It cost 100,000 * .01 = $1,000 a day to keep the place open. He makes 150 * 10 = $1500 a day from the park. So he makes a profit of 1500 - 1000 = $500 a day. So it takes 100000 / 500 = 200 days to make back his money. The answer is 200.
Question: John has a very inefficient toilet that uses 5 gallons of water per flush and his household flushed 15 times per day. He replaced it with a toilet that uses 80% less water per flush. How much water did John save in June?
Answer: He used to use 5 * 15 = 75 gallons of water per day. This means he used 75 * 30 = 2250 gallons a month. His new toilet uses 5 * .8 = 4 gallons less water per flush. So, it only uses 5 - 4 = 1 gallon per flush. That means he uses 1 * 15 = 15 gallons per day. All in all, it accounts for a total usage of 15 * 30 = 450 gallons. So, he saved 2250 - 450 = 1800 gallons per month. The answer is 1800.
[Question]For the gala luncheon planning committee, Margaret wants to serve chicken salad sandwiches using mini croissants. She wants there to be enough food that each person on the committee can have 2 sandwiches each. Her bakery offers 12 minis croissants for $8.00. There are 24 people on the committee. How much will she spend on croissants?
[Answer]There are 24 people on the committee and she wants 2 sandwiches per person so that's 24 * 2 = 48 sandwiches. She can buy the croissants by the dozen and she needs 48 croissants so she needs 48 / 12 = 4 dozen croissants. A dozen croissants cost $8.00 and she needs 4 dozens so that will costs 8 * 4 = $32.00. The answer is 32.
Q: 50% of substitute teachers walk out after 1 hour of teaching. 30% of the remainder quit before lunch. If 60 substitute teachers show up at 7 AM, how many will be left after lunch?
A: First find the number of substitute teachers left after half quit: 60 teachers / 2 = 30 teachers. Then find how many teachers quit after an hour but before lunch: 30 teachers * 30% = 9 teachers. Then subtract that number from the number of teachers left after one hour to find how many are left after lunch: 30 teachers - 9 teachers = 21 teachers. The answer is 21.
