An energy saver heater uses 24% less energy than the older heater model. The older heater uses $350 worth of energy per year. A homeowner replaces his older heater with the new, energy saving heater. Each year how much will he save?

0.24 * 350 = $______

To find out how much the homeowner will save each year, follow these steps:

1. Calculate the amount of energy saved by the new heater compared to the older one. The energy saving heater uses 24% less energy than the older model. This means it uses 100% - 24% = 76% of the energy used by the older heater.

2. Calculate the energy used by the new heater by multiplying the energy used by the older model by 76%:
Energy used by the new heater = $350 × 76% = $266.

3. Calculate the annual savings by subtracting the energy used by the new heater from the energy used by the older heater:
Annual savings = Energy used by the older heater - Energy used by the new heater
= $350 - $266 = $84.

Therefore, the homeowner will save $84 per year by replacing the older heater with the new energy-saving model.
