Question

2) Chloe lives in an area where she only runs the air conditioner during the 4 hottest months of the

year. The air conditioner runs for 7 hours per day at a cost of 25 cents per hour. How much does
she spend per year on utility bills for the air conditioner? (Assume there are 30 days in a month)

Answer 1

Explanation:

she runs the air during the 4 hottest months.....30 days per month....so she runs the air for (30 * 4) = 120 days

she runs it for 7 hrs per day....so she runs it (7 * 120) = 840 hrs

at a cost of 0.25 per hr....(840 * 0.25) = $ 210 <==

Answer 2

D) $176.40

good luck
