## ihatealgebrasomuch 3 years ago 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?

If 25 % of the electricity consumed is used to heat water, what pourcentage of the electricity Jake uses to heat water?

>\$215* 25% >215 * 25/100 >(25 * 125)/100

3025/100?

7. zepp

12. zepp

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
