PLEASE HELP
The commission rate on the sale of a new car is 0.4%. If the commission on one car is
$250, what did the car sell for?

The car was sold for $62,500.

Step-by-step explanation:

This question can be solved by a rule of three.

The commission rate on the sale of a new car is 0.4%

The commission on one car is $250, which means that 250 is 0.4% = 0.004 of the car price. How much is 100% = 1?

0.004 - $250

1 - x

The car was sold for $62,500.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
