A standard showerhead in Reyna's house dispenses 9 gallons of water per minute. Reyna 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 Reyna save each day with the change in showerheads if she uses the shower for 8 minutes each day? (1 point)
14 gallons
48 gallons
69 gallons
96 gallons
To find out how much water Reyna saves each day, we need to compare the amount of water dispensed by the standard showerhead to the amount dispensed by the energy-saving one.
Using the equation y = 3x, we can substitute x = 8 (the number of minutes Reyna uses the shower each day):
y = 3(8) = 24
Therefore, the energy-saving showerhead dispenses 24 gallons of water in 8 minutes.
Comparing this to the standard showerhead, which dispenses 9 gallons of water per minute, we can calculate the total amount of water saved:
9 gallons/minute x 8 minutes = 72 gallons
Therefore, Reyna saves 72 gallons of water each day by using the energy-saving showerhead.
