Question

Chloe lives in an area where she runs the air conditioned runs for 7 hours per day at a cost of 21 cents per hour. How much does spend per year on utility bills for the air conditioner?( assume there are 30 days in each month)

a. $ 705.60
b. $ 588.00
c. $216.09
d. $176.40

Answer 1

$529.20

Explanation:

If there are 30 days in a month and there are 12 months in a year,

30*12 = 360

then there are 360 days in a year

Assuming we run at 7 hours per day

7 hrs/ day * 360 days = 2520 hours

We will run 2520 hours in a year

At $.21 per hour,

.21* 2520 = 529.20

It will cost $529.20 to run the air conditioner for the year
