Question

There are approximately 110 million households that use TVs in the United States. Each TV uses, on average, of power and is turned on for 6.0 hours a day. If electrical energy costs $0.12 per kWh, how much money is spent every day in keeping 110 million TVs turned on?

Answer 1

$5.94 million

Step-by-step explanation:

Each TV uses 75 W of power.

The total Energy spent (E) per TV is kWH is:

`E = 75*10^(-3)*6\\E= 0.45\ kWh`

The total cost (c) per TV is:

`E= \$0.12 * 0.45\\E=\$0.054`

The total cost of keeping 110 million TVs turned on every day (C) is :

`C= \$0.054*110,000,000\\C= \$5,954,000`

It costs 5.94 million dollars to keep 110 million TVs turned on each day.
