x = original price

15% off the original price of the purchase :
x - 0.15x

OR

if u get 15% off, then u are paying for 85%
0.85x

Answer 2

The required expression to the model is 0.85x.

Explanation:

Consider the provided information.

15% off the original price of a purchase.

Let the original price of the product is x.

If you are getting an off of 15% that means that you need to pay 100%-15%=85% of the original price.

85% of the original price (x) can be written as:

`85\% * x`

`(85)/(100)* x`

`0.85* x`

`0.85x`

Thus, the required expression to the model is 0.85x
