How much does it cost to run a 2100 W air conditioner for 10 h at 10 cents per kilowatt - hour round to the nearest cent

So, total cost is 210 cents

Step-by-step explanation:

Given that

Power of Air Conditioner = 2100W

Energy Consumed by in 1 hour = 2100 x 3600s = 7560000

Energy Consumed in Kw-hour in 1 hour = 7560000/3600000

Energy Consumed in Kw-hour in 1 hour = 2.1

Total Running time of Air Conditioner = 10 hours

Cost of per KW - Hour of Air Conditioner = 10 cents

Total Running Cost = ?

As we know

Total Energy Consumed = Total Energy Consumed in 1 hour x Total Running Time

So,

Total Energy Consumed = 2.1 x 10 = 21 KW-hour

Total Cost = Total Energy Consumed x Cost per KW-hour

Total Cost = 21 x 10 = 210 cents

So, total cost is 210 cents
