A video store rents new movies for $5 and older movies for $4. The owner wants
$14000 in revenue per month. How many new movies must be rented if the number of
older movies rented is 400?

2480 new movies

Step-by-step explanation:

1) First you need to find out how much money the 400 older movies made.

2) Next subtract that amount from the amount of revenue that the wants.

3) Divide the amount of leftover money by the amount that a new movie costs to rent

This means that in order to reach the desired amount of revenue the store must sell 2480 new movies.

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

answer:

a=9
