Question: Jame gets a raise to $20 per hour and works 40 hours a week. His old job was $16 an hour for 25 hours per week. How much more money does he make per year in his new job than the old job if he works 52 weeks a year?
Answer: He makes 20 * 40 = $800 per week. He used to make 16 * 25 = $400 per week. So his raise was 800 - 400 = $400 per week. So he makes 400 * 52 = $20,800 per year more. The answer is 20800.
[Question]Ever since she was a little girl, Sheila has dreamed of traveling the world. To help fund her dream, she bought a large piggy bank in December and started saving. By last week, she had saved $3,000. Pleased with her progress, she has decided to continue saving $276 per month, for 4 years. Today, Sheila’s family secretly added $7,000 into the piggy bank. At the end of 4 years, how much money will be in Sheila’s piggy bank?
[Answer]Today, Sheila’s piggy bank has $3000 + $7000 = $10000. Sheila will be saving for 4 years which is equivalent to 12 months / year * 4 years = 48 months. In 4 years, she will save $276 / month * 48 months = $13248. The piggy bank will have a total of $10,000 + $13,248 = $23248. The answer is 23248.

[Question]Tracy has a charity book collection store from which she receives book donations from members of her town. Any person who wants to borrow a book is free to do so as long as they return the book after they've finished reading. She has already received 300 book donations. If ten people come and donate five books each in a week, and a total of 140 books are borrowed by other people to read, calculate the total number of books she has remaining in the store?
[Answer]
The ten people donated 10 * 5 = 50 books. The total number of books in her store after the new donations is 300 + 50 = 350 books. When some of the books are borrowed, her total collection becomes 350 - 140 = 210 books. The answer is 210.
