Consider it to be 2 separate problems:
1. How much water is saved in a one-year period when using an efficiency washer vs regular washer - answer based on your assumptions and calculations for full credit
2. How much water does an average person drink in a lifetime – arrive at this answer based on your assumptions and calculations
