Answer:
A). Commission = $1234.3
B). Purchase of the car = $24790
Step-by-step explanation:
A).The commission earned on the sale of a car is represented by the equation
C(p) = 250 + 0.02p
Where C represents the commission and p represents the purchase price.
If the purchase price of the car is $15075 then
C(p) = 250 + 0.02 × 15075
= 250 + 301.50
= $551.50
If the purchase price of the car was $21640 then
C(p) = 250 + 0.02×(21640)
= 250 + 432.80
= $682.80
Therefore, total commission on these cars = $551.50 + $682.80 = $1234.3
B). If C(p) = 745.80 then we have to calculate the purchase of the car.
745.80 = 250 + 0.02p
0.02p = 745.80 - 250
0.02p = 495.80
p = 
= $24790
Therefore, purchase of the car will be $24790.
