An electric heater has a power of 1100W. At a rate of 8¢ per kWh, how much does it cost to use the heater 3 hours a day for 30 days?
It will cost $7.92 to use the electric heater for 3 hours a day for 30 days at a rate of 8¢ per kWh.
To calculate the cost of using the electric heater for 3 hours a day for 30 days, we need to determine the energy consumption in kWh first.
The power of the electric heater is given as 1100W, which means it consumes 1.1 kWh of energy per hour (since 1 kWh = 1000W). Therefore, the energy consumption in 3 hours is 3.3 kWh (1.1 kWh x 3 hours).
Now, we can calculate the total energy consumption for 30 days, which is 99 kWh (3.3 kWh x 30 days).
Using the given rate of 8¢ per kWh, we can calculate the total cost of using the electric heater for 30 days as follows:
Total Cost = Energy Consumption x Rate per kWh
Total Cost = 99 kWh x 8¢
Total Cost = $7.92
