Question

1. You order books through a catalog. Each book costs $12 and the

shipping and handling cost is $5. Write an equation and make a
graph that represents your total cost.
a. What is the total cost if you buy 6 books?
b. What is the total cost if you buy 4 books?

Answer 1

y=12x+5

Explanation:

y = the total cost

x = the number of books ordered

12x because each book (x) is $12

+5 because shipping and handling is an initial charge of $5

a. y=12(6)+5

y=72+5

y=77

b. y=12(4)+5

y=48+5

y=53
