Astandard 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?

Sonia saves a lot of water. To figure this out, you plug the number 8 into the equation, replacing it with the variable x. y = 3(8). Therefore, y=24. To find out how much water she saves, you have to also figure out how much water she was using for 8 minutes with the other shower head, the one that wastes the water. Since it dispenses 12 gallons per minute, you multiply that by 8 minutes and get 96. Subtract 24 from 96 and get 72. Which I think is your answer. Then again, I'm in high school so I most likely am wrong.

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400
