Answer:

$10.08

Explanation:

There are 24 hours in a day.

Now, if we assume that the refrigerator uses the 200 Watts per hour, thus, in one day, it will consume;

200 x 24 = 4800 watts

Thus, in 30 days, it will consume;

4800 x 30 = 144,000 Watts

Now, 1000 watts = 1KW

Thus,144,000 watts = 144,000/1000 = 144 KW

Now, since the power company charges $0.07 per kWh, thus the cost for 144 KW = 144 x 0.07 = $10.08
