.

Let x be the original price before the discount.


Then the governing equation to find x from the problem is

    (1-0.15)x = 8000,


or, which is the same

    0.85x = 8000.


It gives  x = 8000%2F0.15 = 9411.764706.


Rounded to the closest dollar, it is x = $9,412.


Buying a discounted car, a buyer saves  $9,412 - $8000  = $1,412.

Solved.

Comment from student : You provided two equations in your reply. I have two questions about the first equation.
You said: (1-0.15)x = 8000 Questions: 1. What information in the word problem indicates to subtract 15% from 1?
2. Does the number 1 inside the parentheses represent 100%? If so, you did 100% - 15% = 85% = 0.15. Yes?


My response:   Your suggestions/(guesses)  are correct.

I am very glad that by straining your mind,  you were able to figure this out on your own.
