[Question]Kiaan is doing home delivery of newspapers in his neighborhood of 200 homes. After an hour of work, he has distributed newspapers to 2/5 of the homes. After another 2 hours of working, he realizes he has distributed newspapers to 60 percent of the remaining homes. How many homes does he still need to distribute the newspapers to?
[Answer]After the first hour of work, he has distributed newspapers to 2 / 5 * 200 = 80 homes. The number of homes that still need newspapers is 200 - 80 = 120. Two hours later, the number of homes he has distributed newspapers to is 60 / 100 * 120 = 72 homes. The number of homes he still needs to distribute newspapers to is 120 - 72 = 48 homes. The answer is 48.
Q: 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?
A: 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.
Question: James writes 10 pages an hour. If he writes 5 pages a day to 2 different people, how many hours a week does he spend writing?
Answer: He writes 5 * 2 = 10 pages a day. So he writes 10 * 7 = 70 pages a week. That means he writes for 70 / 10 = 7 hours. The answer is 7.
[Question]Matt did his homework for 150 minutes. He spent 30% of that time on math and 40% on science. He spent the remaining time on other subjects. How much time did Matt spend on homework in other subjects?
[Answer]Matt spent on math and science 30% + 40% = 70% of the time. This means he did homework from these two subjects for 70 / 100 * 150 minutes = 105 minutes. So Matt spent 150 minutes - 105 minutes = 45 minutes doing homework from other subjects. The answer is 45.
Q: Markese earned 5 fewer dollars than Evan. Together they earned $37. How many dollars did Markese earn? Use E to represent how many dollars Evan earned.
