A refrigerator using 1014 W runs two-thirds of the time. How much does the electricity cost to run the refrigerator each month (30 days) at 30¢ per kWh?
First, we need to calculate the total energy consumed by the refrigerator in one day.
Power consumption per hour = 1014 W
Power consumption per day = 1014 W x 24 hours = 24336 Wh or 24.336 kWh
Since the refrigerator runs two-thirds of the time, it consumes 16.224 kWh per day.
Next, we need to calculate the total cost of running the refrigerator for 30 days.
Cost per day = 16.224 kWh x $0.30 = $4.87 per day
Total cost for 30 days = $4.87 x 30 = $146.10
Therefore, the electricity cost to run the refrigerator each month at 30¢ per kWh is $146.10.
