Example: Your office supplies dealer is selling selected stock at 25% off. Create
a program that calculates the net cost of an item after the discount is subtracted
and the $5 handling charge is added.
First, we'll manually calculate the net cost of an item listing for $200.

Finally, press the keys that we used above to solve the problem manually. Do not
key in 200; this number will vary each time the program is used. Don't be
concerned right now about what appears in the display as you press the keys;
we'll discuss that later in this section.
