[Question]Jamie's father gained 5 pounds over the holidays that he wants to lose so his pants will not be as snug. He asks Jamie to help him keep track of his calories. Jamie's father burns 2,500 calories of fat a day by doing light exercise. There are 3,500 calories in a pound of body fat. How many days will it take for Jamie's father to burn off 5 pounds if he does light exercise and sticks to eating 2000 calories a day?
[Answer]First Jamie wants to figure out how many calories his father needs to lose from 5 pounds x 3500 calories each = 17,500 calories to burn off. Then Jamie needs to figure out how many calories his father will burn per day if he burns 2500 calories - eating 2000 calories = burning 500 calories a day. If Jamie's father wants to burn off 17,500 calories total at 500 calories a day, 17,500 / 500 = 35 days to burn off 5 pounds. The answer is 35.
Q: Kevin has a shoebox filled with toads. Every day, Kevin feeds each toad 3 worms. It takes Kevin 15 minutes to find each worm. If it takes Kevin 6 hours to find enough worms to feed all of his toads, how many toads does Kevin have in his shoebox?
A: If it takes 15 minutes to find each worm, then he catches 60 / 15 = 4 worms per hour. In 6 hours, Kevin catches 4 * 6 = 24 worms. If he feeds each toad 3 worms, then he has 24 / 3 = 8 toads in his shoebox. The answer is 8.
Question: John adopts a dog from a shelter. The dog ends up having health problems and this requires 3 vet appointments, which cost $400 each. After the first appointment, John paid $100 for pet insurance that covers 80% of the subsequent visits. How much did he pay in total?
Answer: He got a discount of 400 * .8 = $320. He got that discount for 3 - 1 = 2 visits. So each of those visits cost 400 - 320 = $80. So he paid 2 * 80 = $160 for those visits. That means he paid a total of 400 + 160 + 100 = $660. The answer is 660.
[Question]Steve bought $25 worth of groceries. He bought a gallon of milk for $3, two boxes of cereal for $3.5 each, 4 bananas for $.25 each, four apples that cost $.5 each and a number of boxes of cookies. The cookies cost twice as much per box as the gallon of milk. How many boxes of cookies did he get?
[Answer]He spent $7 on cereal because 2 x 3.5 = 7. He spent $1 on bananas because 4 x .25 = 1. He spent $2 on apples because 4 x .5 = 2. He spent 13 on everything but the cookies because 3 + 7 + 1 + 2 = 13. He spent $12 on cookies because 25 - 13 = 12. Each box of cookies is $6 because 3 x 2 = 6. He bought 2 boxes of cookies because 12 / 6 = 2. The answer is 2.
[Question]James paints a 20 ft by 15 ft mural. It takes him 20 minutes to paint 1 square foot and he charges $150 per hour. How much does he charge to paint the mural?
[Answer]
The mural is 20 * 15 = 300 square feet. So it takes him 300 * 20 = 6000 minutes. So he paints it in 6000 / 60 = 100 hours. That means he charges 100 * 150 = $15000. The answer is 15000.
