Question

A refrigerator has a broken light bulb inside
that is constantly turned on even when the
refrigerator door is closed. If the light bulb uses
20 W of power and the refrigerator has a COP
of 1.4, what would be the total cost of power
consumption of the entire refrigerator? Assume
electricity costs P12 per kWh and the
refrigerator is opened an average of 15 times
per day for 30 seconds.
