If electricity costs 7.06 cents/kWh, how much would it cost to run a 120 W stereo system for 4.0 hours per day for 28 days?

Note: $1 = 100 cents.

Answer :

it would cost you approximately $0.033888 to run the stereo system for 4.0 hours per day for 28 days, assuming an electricity cost of 7.06 cents/kWh.

To calculate the cost of running a stereo system, we need to determine the total energy consumed and then multiply it by the cost per kilowatt-hour (kWh).

First, let's calculate the total energy consumed:

Energy consumed (in kilowatt-hours) = Power (in watts) * Time (in hours)

Energy consumed = 120 W * 4.0 hours = 480 watt-hours

Next, let's convert the energy consumed to kilowatt-hours:

Energy consumed (in kilowatt-hours) = Energy consumed (in watt-hours) / 1000

Energy consumed = 480 watt-hours / 1000 = 0.48 kilowatt-hours

Now, let's calculate the total cost:

Cost = Energy consumed (in kilowatt-hours) * Cost per kilowatt-hour

Cost = 0.48 kWh * $0.0706/kWh = $0.033888

Therefore, it would cost you approximately $0.033888 to run the stereo system for 4.0 hours per day for 28 days, assuming an electricity cost of 7.06 cents/kWh.
