A homeowner's electric bill was $94.23 last month. How many kilowatt hours (to the nearest kilowatt hour) were used if the electric company charges $0.1374 per kilowatt-hour plus a basic customer fee of $5.54 per month?

Let x represent the number of kilowatt-hours that were used. Choose the correct equation below. Solve and round to the nearest integer.

A. 5.54-0.1374x=94.23

B. 0.1374x+94.23=5.54

C. 0.1374x+5.54=94.23

D. 0.1374x-5.54=94.23

Answer: 645 kilowatt-hours

Step-by-step explanation:

Let x represent the number of kilowatt-hours that were used.

if the electric company charges $0.1374 per kilowatt-hour plus a basic customer fee of $5.54 per month, it means that the total charge for x kilowatt-hours used in a month is

5.54 + 0.1374x

The homeowner's electric bill was $94.23 last month. Therefore, the equation would be

0.1374x+5.54=94.23

0.1374x = 94.23 - 5.54

0.1374x = 88.69

x = 88.69/0.1374

x = 645
