1. (TCO 10) A retail store is having a customer appreciation sale. Depending on the total dollars purchased, the customer could receive a discount on his or her total purchases. You are to develop pseudocode that will obtain the total dollars purchased from the user, determine the discount percentage, and display the total amount due.
