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.
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
