A standard showerhead in Jen's house dispenses 5 gallons of water per minute. Jen 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 Jen save each day with the change in showerheads if she uses the shower for 8 minutes each day?

a. 16 gallons
b. 17 gallons
c. 32 gallons
d. 37 gallons
