28 Section 1: Getting Started
Example: Before you leave to call on a customer interested in your personal
computer, you store the cost of the computer ($1,250) and also the cost of a
printer ($500) in data storage registers. Later, the customer decides to buy six
computers and one printer. You recall the cost of the computer, multiply by the
quantity ordered, and then recall and add the cost of the printer to get the total
invoice.
