Application #2

Suppose you plan to buy many blank compact discs. When you check price lists, you find that if you buy less than a 1000 CDs you pay $0.74 each. However if you buy between 1000 and 2000 CD's the price drops to $0.69 each for the second thousand. Also, for any purchase of more than 2000, the price for the CD's drops again to $0.64 for each after the 2000 th. This is another example of a piecewise function. There are many real-life applications of piecewise functions found in science and business.
