What criteria did you use to decide which showerhead to buy?

Solution

VerifiedI used the criteria of the unit water usage rate to decide which showerhead to buy. Since each showerhead has an initial value of 0 gallons, then the showerhead with the smallest unit rate will use the least amount of water for any given amount of time.

The Water Miser Showerhead uses 6 gallons in 3 minutes so its unit rate is $\dfrac{6}{3}=2$ gallons per minute. The Watersaver Showerhead uses 5 gallons in 2 minutes so its unit rate is $\dfrac{5}{2}=2.5$ gallons per minute. The Waterstream Showerhead uses 7.5 gallons in 5 minutes so its unit rate is $\dfrac{7.5}{5}=1.5$ gallons per minute. Since the Waterstream Showerhead has the smallest unit rate, it will use the least amount of water for any given amount of time. I would then choose the Waterstream Showerhead.
