Answer:
520 cars
Step-by-step explanation:
Let the car sold in March be x, x+5%*x=546. (105/100)*x=546. x=520
First we take the two points (-7,5) and (-5,9).
Compute the slope:

Then the linear relation may be in the following form

Since the point (-7,5) is on the line, then

The relation is then

.
We check that the other point are on the above line:

W
e have then a linear relation.
