You have deployed the system for Williams & Son and all is going well. Mr. Williams is impressed with the new system's capability and how easy it is to use the system. Because of this, he has asked you to modify the system so that it can automatically calculate discount for the customer based on the total amount of their purchase. Mr. Williams has asked that the discount amount be indicated on the slip as well as the amount due by the customer after discount has been applied. Discounts are awarded based on the following criteria: Sales Amount Discount R0 - R100 0% R101 - R150 5% R151 - R201 10% more than R201 15% Q.3.1 Make a copy of the pseudocode you created in Question 2.1. Then, modify the pseudocode so that the solution will satisfy the following requirements: The solution should make use of a selection structure to determine the percentage discount that the customer is to receive. Once the percentage discount has been determined, the discount amount should be determined. The slip produced should be amended so that it shows the total purchase amount, the amount of discount the customer receives as well as the amount due by the customer after discount has been subtracted from the total purchase amount
