A hot water heater operating at 240 V supplies to a quantity of water to warm it to the desired temperature of . What is the cost of the energy if the rate is $0.131/kWh?

Complete Question:

A hot water heater operating at 240 V supplies 9.07 x 10⁶ joules to a quantity of water to warm it to the desired temperature of 60°C. What is the cost of the energy if the rate is $0.131/kWh?

The cost of the energy is $0.33

Explanation:

Given;

quantity of energy supplied = 9.07 x 10⁶ joules

Converting this energy to kWh = 2.519  kWh

one unit of energy cost $0.131/kWh, then the cost 2.519 kWh will be calculated as follows;

1 kWh $0.131/kWh

2.519 kWh ?

= 2.519 (kWh) * $0.131/kWh

= $0.33

Therefore, if the hot water heater operating at 240 V supplies 9.07 x 10⁶ joules at the rate of $0.131/kWh, then the cost of the energy is $0.33.
