Answer:$720

Step-by-step explanation:Coefficient of performance of a refrigerator (COP) =

desired out i.e energy removed = 600Bth/hr

Required input=?

2.4=

required input==25Btu/hr

cost of electricity per hour = $0.08

cost of electricity for 360 hours =$0.08×360=$28.8

for an input of 25Btu/hr and 360 hours

∴cost of electricity in month =$28.8×25=$720
