Question: Dale owns 4 sports cars. The red one can travel at twice the speed of the green one, but the green one can travel at 8 times the speed of the blue one. The yellow one is broken and cannot move at all. If the blue one can travel at a speed of 80 miles per hour, at what speed, in miles per hour, can the red car travel?
Answer: If the blue car can travel at 80 mph, then the green one can travel at 8 * 80 = 640 mph. If the green car can travel at 640 mph, then the red can travel at 2 * 640 = 1280 mph. The answer is 1280.
[Question]Carmen needs $7 more to have twice the amount of money that Jethro has. Meanwhile, Patricia has $60, which is 3 times as much as Jethro. What is the sum of all their money?
[Answer]Jethro has 60 / 3 = $20. Twice of what Jethro has is $20 x 2 = $40. Carmen has $40 - 7 = $33. The sum of all their money is $60 + $20 + $33 = $113. The answer is 113.
Q: Kim's TV uses 125 watts of electricity per hour. She runs it for 4 hours a day. If electricity cost 14 cents per kw/h how many cents does her TV cost to run for a week?
A: She uses 4 hours / day * 125 watts / hour = 500 watt hours / day. That means she uses 500 watt hours / day * 7 days / week = 3500 watt hours / week. This is 3500 watt hours / 1000 watts / kw = 3.5 kw hours. So her TV cost 3.5 kw hours / week * $0.14 / kw hour = $0.49 / week. The answer is 49.
Question: Javier is selling donuts to raise money for a new game. He wants to raise $96. He buys each dozen donuts for $2.40 and then sells each donut for $1. How many dozen donuts does he need to buy and sell to reach his goal?
Answer: Every donut costs him $.2 because 2.4 divided by 12 equals .2. So he makes $.8 for every donut he sells because $1 minus $.2 equals .8. He needs to sell 120 donuts because 96 divided by .8 equals 120. He needs to buy and sell 10 dozen donuts because 120 divided by 12 equals 10. The answer is 10.
