Question

You are ordering DVD's from a web site. They charge $14 for each DVD. For any order you must pay an additional $6 for shipping and handling. Your total cost is a function of how many DVD's

Answer 1

y = 16x + 6

Explanation:

They charge $14 for each DVD, which mean the slope of the function is 14

You must pay an additional $6 for shipping and handling, which means no matter how many DVD you buy, you have to pay a flat fee for $6

So our function is:

y = 16x + 6 where:

y is total cost

x is the number of DVD you buy (x>0)
