A standard showerhead in Sonia's house dispenses 12 gallons of water per minute. Sonia changed this showerhead to an energysaving 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
