Answer :
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
