1. (TCO 10) A department store is having a customer appreciation sale. Depending on the total dollars purchased, the customer could receive a discount on total purchases. You are to develop pseudocode that will obtain the total dollars purchased from the user, determine the discount percent, and display the total amount due. When the purchases are more than $500, the discount is 10%. When the purchases are $500 or less, the discount is 6%. (Points : 10)
