Answer 1

The previous reading on Bill Heckle's electric bill is 21,780 kWh.

The present reading is 24,100 kWh. Bill used 2,320 kWh of electricity during the service period.

Wattco charged $0.11 per kilowatt-hour of electricity.

Bill's average daily expense for electricity for this service period is $8.23 per day.

Step-by-step explanation:

The previous reading on Bill Heckle's electric bill is 21,780 kWh.

The present reading on Bill Heckle's electric bill is 24,100 kWh.

To find the number of kilowatt-hours of electricity Bill used during the service period, subtract the previous reading from the present reading:

24,100 kWh - 21,780 kWh

= 2,320 kWh.

The electric company, Wattco, charged $255.20 for 2,320 kWh of electricity.

To find the cost per kilowatt-hour, divide the amount by the usage:

$255.20 / 2,320 kWh

= $0.11 per kilowatt-hour.

To calculate Bill's average daily expense for electricity for this service period, divide the total amount by the number of days in the service period:

$255.20 / 31 days

= $8.23 per day.
