Final answer:

The cost of each book Jason bought can be found by solving the equation 3x - 2 = 13, which leads to x being $5 per book after applying arithmetic operations to isolate x.

Step-by-step explanation:

To determine the cost of each book Jason bought, we can set up an equation where x represents the cost of one book. Since he bought 3 books and had a $2 coupon, the equation incorporating the total spent would be:

3x - 2 = 13

To solve for x, you would add 2 to both sides of the equation to isolate the term with x, which gives you 3x = 15.

Then, you divide both sides by 3 to find the value of x, which results in x being $5, the cost of one book.
