Question

A standard showerhead in Sonia's house dispenses 12 gallons of water per minute. Sonia changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x How much water does Sonia save each day with the change in showerheads if she uses the shower for 8 minutes each day? 9 gallons 17 gallons 72 gallons 93 gallons

Answer 1

Using the new head uses 3 × 8 = 24 gallons

saving = 96 - 24 = 72 gallons
