Q: Maggie has an after-school job that pays her $5.00 for every magazine subscription she can sell. She sells 4 to her parents, 1 to her grandfather, 2 to the next-door neighbor and twice that amount to another neighbor. How much money did Maggie earn?
A: Maggie sells 2 subscriptions to a neighbor and twice that amount to another neighbor so she sells 2 * 2 = 4 subscriptions to the other neighbor. In total, Maggie sells 4 + 1 + 2 + 4 = 11 subscriptions. She earns $5.00 per subscription she sells so she earns 5 * 11 = $55.00. The answer is 55.
Question: Jangshe spent $610 on 7 pieces of clothing. One piece was $49 and another piece was $81. If the other pieces were all the same price, how many dollars was one of the other pieces?
Answer: 610 - 49 = 561, and then 561 - 81 = 480. There were 7 - 2 = 5 other pieces. 480 / 5 = 96 dollars. The other 5 pieces cost $96 each. The answer is 96.
[Question]Some friends went hiking for 3.5 hours. They traveled 21 kilometers in that time. Birgit was 4 minutes/km faster than the average time. If Birgit kept the same pace, how many minutes would it take her to go 8 kilometers?
[Answer]Minutes spent hiking = 3.5 * 60 = 210 minutes. Average speed = 210 minutes / 21 km = 10 minutes / km. Birgit is 4 minutes / km faster = 10 - 4 = 6 min / km. It would take 6 * 8 = 48 minutes to go 8 km. Birgit would take 48 minutes to travel 8 kilometers. The answer is 48.
Q: Amanda charges $20.00 per hour to help clean out and organize a person's home. She has 5 1.5 hours appointments on Monday, a 3-hours appointment on Tuesday and 2 2-hours appointments on Thursday. On Saturday, she will spend 6 hours at one client's house. How much money will she make this week?
A: She has 5 1.5 hour appointments on Monday for a total of 5 * 1.5 = 7.5 hours. She has 2 2 hour appointments on Thursday for a total of 2 * 2 = 4 hours. She is working 7.5 hours on Monday, 3 hours on Tuesday, 4 hours on Thursday and 6 hours on Saturday for a total of 7.5 + 3 + 4 + 6 = 20.5 hours. She charges $20.00 an hour and is working 20.5 hours a week for a total of 20 * 20.5 = $410.00. The answer is 410.
Question: 1/3 of the townspeople have received the full COVID vaccine. 1/3 are immune because they already recovered from COVID. If 1/6 of the townspeople are both vaccinated and already had COVID, what percent of the town is immune in some way?
Answer: First add the fractions of vaccinated and recovered townspeople: 1 / 3 + 1 / 3 = 2 / 3. Then you need to subtract the fraction that are both vaccinated and recovered, since they were double - counted. To do this, start by converting 2 / 3 to the same denominator as 1 / 6: 2 / 3 * 2 / 2 = 4 / 6. Then subtract 1 / 6 from 4 / 6: 4 / 6 - 1 / 6 = 3 / 6. Then divide the numerator by the denominator and multiply by 100% to express the answer as a percentage: 3 / 6 * 100% = 50%. The answer is 50.
Q: Ray has 175 cents in nickels. Ray gives 30 cents to Peter, and he gives twice as many cents to Randi as he gave to Peter. How many more nickels does Randi have than Peter?
A:
Ray gave 30 * 2 = 60 cents to Randi. Randi has 60 / 5 = 12 nickels. Peter has 30 / 5 = 6 nickels. Randi has 12 - 6 = 6 more nickels than Peter. The answer is 6.
