An electric company charges $0.15 for each kilowatt-hour of electricity. If your electric bill is $67.50, how many kilowatt- hours of electricity did you use?

Respuesta :

Answer:

450 kilo watt hour of electricity was used

Step-by-step explanation:

Here, we are interested in calculating the kilowatt-hour of electricity used.

From the question, we are told that the bill is $67.50 and the cost of 1 kilo watt hour is $0.15

So to know the amount of kilowatt hours of electricity used, we will simply divide the bill by the charge per 1 kwh

Mathematically that would be 67.5/0.15 = 450
