Q: 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?
A: 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 factory produces 90 refrigerators per hour. It also produces 70 more coolers than refrigerators per hour. How many products did the factory produce for 5 days if it works 9 hours a day?
A: The factory produces 90 + 70 = 160 coolers per hour. The factory works 5 * 9 = 45 hours in 5 days. The factory produces ( 90 + 160) * 45 = 11250 products for 5 days. The answer is 11250.

Q: Wade has called into a rest stop and decides to get food for the road. He buys a sandwich to eat now, one for the road, and one for in the evening. He also buys 2 drinks. If the drinks cost $4 each and Wade spends a total of $26 then how much, in dollars, did the sandwiches each cost?
A:
The drinks cost a total of $4 per drink * 2 drinks = $8. So the sandwiches cost a total of $26 total spending - $8 spending on drinks = $18. Therefore, each sandwich costs $18 for sandwiches / 3 sandwiches = $6. The answer is 6.
