There are approximately 113 million TVs in the United States. Each uses, on average, 76 W of power and is turned on for 6.3 hour
ioda

Answer:

76 W *\frac{1kW}{1000 W}= 0.076 kW

0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}

113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh

And finally we can convert this into money like this:

54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6

So they spent every day approximately in total $ 4815291.6 dollars

Step-by-step explanation:

For this case we can convert the average power into Kw like this:

76 W *\frac{1kW}{1000 W}= 0.076 kW

Now on average we know that one person use on average this power over 6.3 hours per day so then we have the following consumption rate:

0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}

And now we know the total population so then the total consumption per day would be:

113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh

And finally we can convert this into money like this:

54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6

So they spent every day approximately in total $ 4815291.6 dollars

In the 1980s an average mortgage rate was around 18.5 how much less per month would a 150000 30 year mortgage by today if the cu
lianna [129]

Answer:

  $1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

  A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

  A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.
