Answer:
$52.50.
Step-by-step explanation:
Since Val's air conditioner uses 3,500 watts when running, and that Val uses it for 5 hours during summer days, spending 10 cents per kilowatt hour, determining how much money Val will spend during a 30-day summer must be done the following calculation:
3,500 watts = 3.5 kilowatts
3.5 kilowatts per hour = 35 cents
35 cents x 5 hours = 175 cents per day
175 cents per day x 30 days = 5250 cents per month
5250/100 = X
52.5 = X
Thus, during 30 days of summer, Val will spend $ 52.50 on electricity from the use of his air conditionier.
