HELPPP I NEED THIS IN % MINUTES PLEASE!!!!!!!!!!!?

Suppose you move into a new house and need to purchase a washing machine. You've heard that the new front-loading machines use less water, but that they are more expensive. A traditional washing machine costs $300, whereas the water efficient washing machines cost $900. So how do you choose?

1. If the average family washes 300 loads of laundry per year, and traditional washing machines use 100 Liters more water per load than water efficient machines, how many liters would an effecient washing machine save per year?

2. If the average cost of water in the United States is .50 cents for every 1,000 liters, how much money would you save annually by using the more efficient washing machine?

3. Given your calculated annual savings, how many years would it take for your water savings to pay for the more expensive, high efficiency washer?
