Q: Andy works in the pro shop at a tennis resort, where he earns $9 an hour. In addition to this, he gets paid $15 for each racquet he restrings, $10 for changing out the grommets on a racquet, and $1 for painting a stencil on the racquet strings. How much does he earn (before taxes) during an 8-hour shift if he strings 7 racquets, changes 2 sets of grommets, and paints 5 stencils?
A: Andy works 8 hours, so he earns a wage of 8 hours * $9 per hour = $72 just for working there. During that time, he restrings 7 racquets, so he earns 7 racquets * $15 per racquet = $105 from stringing. He also changed the grommets in 2 of those racquets, so he earned 2 grommet jobs * $10 per grommet job = $20 from changing grommets. And he stenciled 5 racquets, so he earned 5 stencil jobs * $1 per stencil job = $5 for stenciling. In total, Andy earned $72 + $105 + $20 + 5 = $202 for the day. The answer is 202.
Question: Lucy works in a pet shop. She can clean 2 aquariums in 3 hours. If Lucy is working 24 hours this week, how many aquariums could she clean?
Answer: We know how many aquariums Lucy can clean in a 3 - hour increment. This week, Lucy will work for 24 / 3 = 8 increments. Lucy can clean 2 aquariums per increment, so she can clean 2 x 8 = 16 aquariums. The answer is 16.
[Question]A boat is traveling across a square lake at 10 MPH. It takes 2 hours to go across the length of the lake. It then travels the whole width of the lake at the same speed, which takes 30 minutes. How many square miles is the lake?
[Answer]The lake is 20 miles across because 2 x 10 = 20. If takes .5 hours to go from bottom to top because 30 / 60 = .5. The lake is five miles from bottom to top because 10 x .5 = 5. The square mileage is 100 because 20 x 5 = 100. The answer is 100.
Q: Billy's mom sends him to get ketchup. She gives him $10 and tells him to get the best deal on ketchup that he can and to spend all $10 on ketchup. He finds a bottle with 10 oz that cost $1 each. He finds a bottle that costs $2 that contains 16 ounces. He finds a bottle with 25 ounces that costs $2.5. He finds a $5 bottle that contains 50 ounces. Finally, he finds a $10 bottle with 200 ounces. How many bottles of ketchup does he buy?
A: The 10 ounce bottle costs $.1 an ounce because 1 / 10 = .1. The 16 ounce bottle costs $.125 an ounce because 2 / 12 = .125. The 25 ounce bottle costs $.125 an ounce because 2.5 / 20 = .125. The 50 ounce bottle costs $.1 an ounce because 5 / 50 = .1. The 200 ounce bottle cost $.05 an ounce because 10 / 200 = .05. The 200 ounce bottle is the cheapest per ounce because .05 < .08 < .1 < .125. He buys 1 bottle of ketchup because 10 / 10 = 1. The answer is 1.
Question: It takes a dog groomer 10 minutes to dry a short-haired dog like a beagle. It takes him twice as long to dry a full-haired, fluffy dog like a german shepherd. One morning, he has 6 short-haired dogs to dry and 9 full-haired dogs to dry. How many hours does it take him to dry all of the dogs?
Answer:
It takes 10 minutes to dry the coat of a short - haired dog and twice as long for a full haired dog so they take 10 * 2 = 20 minutes to dry. He had 6 short hair dogs and they took 10 minutes to dry each so they took 6 * 10 = 60 minutes to dry. He had 9 full haired dogs that took 20 minutes to dry each so they took 9 * 20 = 180 minutes to dry. Together is takes him 60 + 180 = 240 minutes to dry all of the dogs. 60 minutes are in 1 hour and he spends 240 minutes on the dogs so he worked for 240 / 60 = 4 hours drying the dogs. The answer is 4.
