The average television is said to be on 6.00 hours per day. Estimate the yearly cost of electricity to operate 100 million TVs, assuming their power consumption averages 139 W and the cost of electricity averages 12.0 cents/kW⋅h . To solve this problem you will first have to calculate the yearly cost of running one television. What is the average yearly cost to operate one television?
