Last month, your electric bill was $25.32 for 450 kilowatt-hours of electricity. At that rate, what would be the bill for 240 kilowatt-hours?
450 /25.32 should = 17.77 approx. then you multiply 240 as the kilowatt rate
To calculate the bill for 240 kilowatt-hours at the same rate as last month, we can use the following formula:
Bill = Rate * Kilowatt-hours
First, we need to determine the rate per kilowatt-hour. We can do this by dividing the total bill by the total kilowatt-hours from last month:
Rate = Bill / Kilowatt-hours
Let's calculate the rate:
Rate = $25.32 / 450 kilowatt-hours
Dividing the total bill ($25.32) by the total kilowatt-hours (450) will give us the rate per kilowatt-hour.
Rate = $0.0563 per kilowatt-hour (rounded to four decimal places)
Now that we have the rate, we can calculate the bill for 240 kilowatt-hours:
Bill = Rate * Kilowatt-hours
Bill = $0.0563 * 240 kilowatt-hours
Multiplying the rate ($0.0563) by the kilowatt-hours (240) will give us the bill.
Bill = $13.51
So, the bill for 240 kilowatt-hours, at the same rate as last month, would be $13.51.
