[Question]: A washing machine uses 20 gallons of water for a heavy wash, 10 gallons of water for a regular wash, and 2 gallons of water for a light wash per load of laundry. If bleach is used, there is an extra light wash cycle added to rinse the laundry thoroughly. There are two heavy washes, three regular washes, and one light wash to do. Two of the loads need to be bleached. How many gallons of water will be needed?
[Answer]: The two heavy washes will use 20 * 2 = 40 gallons of water. The three regular washes will use 10 * 3 = 30 gallons of water. The light wash will use 2 * 1 = 2 gallons of water. The two bleached loads will use an extra 2 * 2 = 4 gallons of water. In all, 40 + 30 + 2 + 4 = 76 gallons of water will be needed.
So the answer is 76.

[Question]: There are many CDs in the store. The rock and roll CDs are $5 each, the pop CDs are $10 each, the dance CDs are $3 each, and the country CDs are $7 each. Julia wants to buy 4 of each, but she only has 75 dollars. How much money is she short?
[Answer]: Rock and Roll CDs will be 5 * 4 = 20 dollars. Pop CDs will be 10 * 4 = 40 dollars. Dance CDs will be 3 * 4 = 12 dollars. Country CDs will be 7 * 4 = 28 dollars. In total Julia would need 20 + 40 + 12 + 28 = 100 dollars. Julia is short 100 - 75 = 25 dollars.
So the answer is 25.

[Question]: Kate saved $27 in March. She saved $13 in April and $28 in May. Then Kate spent $49 on a keyboard and $5 on a mouse. How much money does Kate have left?
