Q: Megan’s grandma gave her $125 to start a savings account. She was able to increase the account by 25% from funds she earned babysitting. Then it decreased by 20% when she bought a new pair of shoes. Her final balance is what percentage of her starting balance?
A: Megan started with $125 and increased it by 25%, so $125 + (0.25)125 or $125 + $31.25 = $156.25. Then the balance decreased by 20%, so $156.25 – (0.20)156.25 or $156.25 - $31.25 = $125. $125 is the balance Megan started with, so her final balance is 100% of the starting balance. The answer is 100.
Question: Anahi bought a 500 pages book to write some notes on. In the first week, she wrote on 150 pages. In the second week, she wrote on 30% of the remaining pages. While continuing writing, she accidentally spilled coffee on the book and damaged 20 percent of the empty pages she was to write on. Calculate the total number of empty pages available for her to write on now.
Answer: If she bought a 500 pages book and wrote on 150 pages, the number of empty pages remaining is 500 - 150 = 350 pages. She then wrote on 30% of the remaining empty pages on the second week, a total of 30 / 100 * 350 = 105 pages. The number of remaining empty pages is 350 - 105 = 245 pages. When she spilled coffee on the remaining empty pages, the number of damaged pages was 20 / 100 * 245 = 49. The number of empty pages remaining that she could write on is 245 - 49 = 196 pages. The answer is 196.
[Question]Care and Rick have a repair shop. Each repair is priced differently: phone repair costs $11, laptop repair costs $15 and computer repair costs $18. If they perform 5 phone repairs, 2 laptop repairs, and 2 computer repairs for this week, how much did they earn for the week?
[Answer]They earned $11 x 5 = $55 for the phone repairs. They earned $15 x 2 = $30 for the laptop repairs. They also earned $18 x 2 = $36 for computer repairs. Therefore, Care and Rick earned $55 + $30 + $36 = $121 for the week. The answer is 121.
Q: Carlson bought land that cost $8000 and additional land that cost $4000. He initially owned 300 square meters of land. If the land he bought costs $20 per square meter, how big is his land after buying the new land?
A: Carlson bought land that cost $20 per square meter, therefore the size of the land he bought is 8000 / 20 = 400. And the size of the other land he bought is 4000 / 20 = 200. Therefore the total size of the land he owns is 400 + 200 + 300 = 900. The answer is 900.
Question: Martha has 20 apples. She decided to split them among her friends. Jane got 5 apples from her, and James got 2 more than Jane. How many more apples would Martha need to give away to be left with only 4 of them?
Answer: Martha gave James 5 + 2 = 7 apples. So Martha was left with 20 - 5 - 7 = 8 apples. To be left with only 4 apples, Martha would need to give away 8 - 4 = 4 more apples. The answer is 4.
Q: Patricia and Geoffrey went fishing to feed their group of campers. They caught an eight-pound trout, six two-pound bass, and two twelve-pound salmon. If each person will eat two pounds of fish, how many campers can they feed?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The bass weigh 6 * 2 = 12 pounds in all. The salmon weigh 2 * 12 = 24 pounds in all. The trout, bass, and salmon together weigh 8 + 12 + 24 = 44 pounds. Each camper will eat 2 pounds of fish, so Patricia and Jeffrey can feed 44 / 2 = 22 campers. The answer is 22.
