The cost of electricity in Los Angeles is 21.5 cents per kWh. A typical freezer uses 4.5 kWh per day when operated continuously, and a typical washing machine uses 9 kWh per month. What would be the approximate cost, in dollars, of operating a washing machine and a freezer for 1 year in Los Angeles?

$34.83
$376.36
$717.89
$1,059.41

34.83

Step-by-step explanation:

4.5kwh+ 9kwh Is 13.5kwh which is how much is being used with both the freezer and a washing machine

It cost 21.5 per kWh so multiply 13.5 by 21.5 to get 290.25

To see what it would be in a year multiply 290.25 by 12(months in a year) to get 3483

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
