UCSS Math III 4B.4.2 Example 1

A wholesale store sells paper plates for $3.27 per package, up to and including 50 packages purchased. If a customer buys more than 50 packages, the price of the entire purchase drops to $2.73 per package. Write a piecewise function for this pricing structure, and determine the price a deli owner would pay for 75 packages of plates.
