1. You take one shower a day for 10 minutes. How much water will you save each year if you install a low-flow showerhead in your home or apartment? Low-flow showerheads use 2.5 gallons of water each minute as opposed to an older model showerhead that uses 4 gallons per minute.

2. If you then shorten your shower time to 5 minutes in addition to using a low-flow showerhead, how much water will be saved for the year?
