Question

A 120 kilowatt light bulb uses about 0.1 kilowatt of electricity per hour if electricity cost $0.20

per kilowatt-hour how much does it cost to have the bulb on for an hour

Answer 1

To find this out we would need to do 120 x $0.20.
120 x $0.20 =$24
So, it would cost about $24 for 1 hour.
Hope This Helps!
