ABC Printing Company charges a $10.00 service fee plus $.02 per copy. Write and evaluate a function rule to find the Total cost of printing 20 copies.

Question

y = mx + b 

 

10.00 service fee

 

plus an additional .02 dollars per copy

 

How much would it cost to print 20 copies

Answer 1

If every copy costs 0.02 dollars, that means to find the cost for your printing you'll need to multiply 0.02 by the number of copies you print. Then, you'll need to add the 10 dollar service fee. So:

 

y = 0.02x + 10

 

That means you're paying $0.02 for every copy, plus $10 no matter how many copies you print.

 

Plug in x = 20 to find out how much it would cost to print 20 copies.
