Question

At a bookstore, you buy a calendar for $3 and some books for $4 each. You spend a total of $23. How many books did you buy?

Answer 1

Answer:

Step-by-step explanation:

3 + 4b = 23....with b representing # of books

4b = 23 - 3

4b = 20

b = 20/4

b = 5 <=== 5 books were bought

Answer 2

5 because subtract 3 from 23 and divide 4 from 20
