At a silk screen shirt company, they charge the following to make shirts:
• An initial charge of $20 to create the silk screen
• $17.00 per shirt for orders of 50 or fewer shirts
• $15.80 per shirt for orders of more than 50 shirts
Write a piecewise function that gives the cost C for an order of x shirts. Graph the function.
