Section 8: Programming Basics 105 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.

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.
