You are looking at your power bill for the month, you pay 15 cents per kilowatt-hour. Your power bill came out to $70.74 how many KWH of energy were used in your house this month?​

The number of kilowatt-hours used KWH is 471.6 KWH.

Since the power bill for the month says you pay 15 cents per kilowatt-hour, this is the rate of the bill. We convert this a a dollar rate.

So, 15 cents per kilowatt-hour = 15 cents × $ 1/100 cents per kilowatt-hour (since $ 1 = 100 cents)

= 15 cents/100 × $ 1/100 cents per kilowatt-hour

= 0.15 × $ 1/100 cents per kilowatt-hour

= $ 0.15 cents per kilowatt-hour.

Since the power bill came out to be $ 70.74, we need to find the number of kilowatt-hours used KWH.

The total amount on bill = rate of bill × number of kilowatt-hours used.

So, number of kilowatt-hours used = total amount on bill/rate of bill

Total amount on bill = $ 70.74 and rate of bill =  $ 0.15 cents per kilowatt-hour.

So, number of kilowatt-hours used = total amount on bill/rate of bill

number of kilowatt-hours used = $ 70.74 /$ 0.15 cents per kilowatt-hour.

number of kilowatt-hours used = 471.6 KWH

So, number of kilowatt-hours used KWH is 471.6 KWH.
