Question: Mr. and Mrs. McPherson have to renew their rent by the end of the year. They agreed that Mrs. McPherson would raise 30% of the money. If their rent is $1200 per year, how much does Mr. McPherson need to raise to complete the rent?
Answer: 30% of $1200 is (30 / 100) * $1200 = $360. Mrs. McPherson will pay $360 leaving $1200 - $360 = $840 which Mr. McPherson will have to raise. The answer is 840.

Q: A vendor bought apples at 2 for $3 and plans to sell them at 5 for $10. He also bought 3 oranges for $2.70 and plans to sell them at $1 each. How much is his profit if he sells 5 apples and 5 oranges?
A: A vendor bought each apple for $3 / 2 = $1.50. He will sell each apple at $10 / 5 = $2 each. His profit for each apple is $2 - $1.50 = $0.50. His total profit for 5 apples is $0.50 x 5 = $2.50. He bought each orange for $2.70 / 3 = $0.90. His profit for each orange is $1 - $0.90 = $0.10. His total profit for 5 oranges is $0.10 x 5 = $0.50. Therefore, his total profit for selling 5 apples and 5 oranges is $2.50 + $0.50 = $3. The answer is 3.
Question: Bob is going to put in a vegetable garden on his property. It's going to be in one of the back corners of his land. He wants the width of the garden to be about an eighth of the width of his property, and the length to be a tenth of the length of his property. His land is 1000 feet wide and 2250 feet long. How many square feet is his garden going to be?
Answer: The width of his garden is going to be 1000 / 8 = 125 feet. The length of his garden is going to be 2250 / 10 = 225 feet. So the area of his garden is going to be 125 X 225 = 28125 square feet. The answer is 28125.
[Question]Jen buys and sells candy bars. She buys candy bars for 80 cents each and sells them for a dollar each. If she buys 50 candy bars and sells 48 of them, how much profit does she make in cents?
[Answer]It costs Jen 80 * 50 = 4000 cents to buy 50 candy bars. Since a dollar is 100 cents, she earns 48 * 100 = 4800 cents by selling 48 of them. Thus her total profit is 4800 - 4000 = 800 cents. The answer is 800.
