Answer:

b = 17

Step-by-step explanation:

The correct equation is 3b - 6 = 45. You get this by saying the books (b) are 3 dollars each (3b) and you are getting a discount of 6 dollars off (- 6). The total after the discount is 45 dollars. You know have to solve this equation for b (the number of books) to get the answer. When you solve this equation, you get b = 17.
