It costs $12.99 to print 20 resumes.  Every 10 more resumes cost $3.  Write a piecewise function for the cost of the resumes, r(x).  How much does it cost produce 60 resumes?

Write a piecewise function for each graph.

The cost of renting a canoe is $20 for the first 4 hours and $3 per hour for additional hours. Sketch a graph of the cost of renting a canoe from 0 to 8 hours. Then write a piecewise function for the graph.

15) Rewrite as a piecewise function: y-x-2-4
