Answer 1

Answer:

3b - 6 = 45 and b = 17

Step-by-step explanation:

3b - 6 = 45 is your equation you get

3b is how many books you bought and the price multiplied by one another, then subtracting 6 gives you the discounted price which is 45

3b - 6 = 45

+6          +6

3b = 51

/3     /3

b = 17

a book costs 17 dollars.

so b = 17  

Answer 2

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.
