Chloe lives in an area where she 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 21 cents per hour. how much does she spend per year on utility bills for the air conditioner? (assume there are 30 days in each month

Assuming there are 30 days in each month, 4 months = 30 * 4 = 120 days.

Running 7 hours per day for 120 days gives us 7 * 120 = 840 hours in total.

We know the cost per hour is $0.21, so in 840 hours the cost would be 840 * 0.21 = $176.4

Per year $176.4 spent on air conditioning.
