Question

The cost of electricity in Los Angeles is 21.5 cents per kWh. A typical freezer uses 4.5 kWh per day when operated continuously, and a typical washing machine uses 9 kWh per month. What would be the approximate cost, in dollars, of operating a washing machine and a freezer for 1 year in Los Angeles?
$34.83
$376.36
$717.89
$1,059.41

Answer 1

Answer:34.83

Step-by-step explanation:

4.5kwh+ 9kwh Is 13.5kwh which is how much is being used with both the freezer and a washing machine

It cost 21.5 per kWh so multiply 13.5 by 21.5 to get 290.25

To see what it would be in a year multiply 290.25 by 12(months in a year) to get 3483
