B. y = x - 2

Step-by-step explanation:

The sale price (y) is $2 less than the original price (x - 2).

To test this out, if a book's original price is $10..

x = 10

Using y = x - 2 and to test out if it works, we'll plug in x = 10 to discover y.

y = 10 - 2

y = 8

i think that you should ask google for the answer to that problem because if we don't know it google does

the answer is 1030 it's very simple math.
