Question

The average television is said to be on 6 hours per day. Estimate the yearly cost of electricity to operate 100 million TVs, assuming their power consumption averages 150 W and the cost of electricity averages 12.0 cents/kW⋅h.

a. $262.80 million
b. $365.25 million
c. $438.30 million
d. $547.50 million

Answer 1

The yearly cost to operate 100 million TVs for 6 hours each day at 150 W per TV and an electricity cost of 12.0 cents/kWh is approximately $3,942,000,000, which does not match any of the provided options.

Step-by-step explanation:

The yearly cost of electricity to operate 100 million TVs, which are on for an average of 6 hours per day, using a power consumption of 150 W per TV can be calculated as follows:

• First, convert the power consumption to kilowatts: 150 W = 0.15 kW.
• Multiply the power consumption by the number of hours per day and the number of days in a year to find the annual energy usage per TV: 0.15 kW * 6 hours/day * 365 days/year = 328.5 kWh/year.
• Calculate the total energy usage for 100 million TVs: 328.5 kWh * 100,000,000 TVs = 32,850,000,000 kWh/year.
• Finally, multiply the total energy usage by the cost of electricity: 32,850,000,000 kWh/year * $0.12/kWh = $3,942,000,000/year.

Therefore, the closest estimate to the yearly cost is $3,942,000,000, which is not one of the provided options. It seems there may be a mistake in the question or the available choices.
