Question

If electricity costs $0.18 per kwh, how much does it cost to run the air conditioner in the problem above?

A)$5.76
B)$7.87
C)$9.45
D)$12.12

Answer 1

the answer is A) $5.76.

We found in the previous problem that the air conditioner uses 32 kWh per day. To find the cost, we multiply the number of kWh by the cost per kWh:

32 kWh/day x $0.18/kWh = $5.76/day

So, it costs $5.76 per day to run the air conditioner.

Therefore, the answer is A) $5.76.
