study island help please-- Around 25 percent of the electricity consumed by American households is used to heat water. Jake's average monthly electricity bill is $215. If Jake installs a solar-powered water heater that does not use any electricity, about how much money will he save on electricity every month?

    Ah, didn't double check your answers >.> (25 * 125)/100 25*125 is 5375 not 3025 5375/100 = $53.75 And I don't get why it would be $50
