Calculate the cost of running an electric laundry iron for 8 hours, if the cost of 1 unit of energy is N24.00 and the rating of the iron is 1200w,240v​

Cost of energy = N230.4

Explanation:

Given the following data;

Time = 8 hours

Power = 1200 W

Voltage = 240 V

Cost of energy = N24

To find the cost of running an electric laundry iron;

First of all, we would determine the energy consumption of the iron.

Energy = power * time

Energy = 1200 * 8

Energy = 9600 Watt-hour = 9.6 Kwh (1 Kilowatts is equal to 1000 watts).

Next, we find the cost of energy;

Cost of energy = 9.6 * 24

Cost of energy = N230.4
