5. 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) 2. (TCO 10) A small business in your neighborhood would like an application developed that determines the average dollar amount spent for every three purchases. The user will enter three different purchase amounts. You need to display the average to your client. Complete the pseudocode to design your logic. (Points : 10) 3. (TCO 9 & 10) There is a logic error in the following pseudocode. What statement(s) would you need to add to correct the logic? Be sure to explain why you are adding the statements. Set DOWHILE num Set + num ENDO Display total (Points : 10) 4. (TCO 4 & 10) Complete the pseudocode by rewriting the algorithm. The design is determining the correct sales tax depending on the county identifying code. Counties with a number less than 7 have a 5% sales tax. The 8-24 codes have a sales tax of 7%. Codes above 24 have a sales tax of 9%. The code is entered by the user.

W HEN YOU MIX TWO PRIMARY COLORS, YOU GET A SECONDARY COLOR. M IXING YELLOW AND BLUE GETS YOU GREEN. M IXING RED AND BLUE GETS YOU PURPLE. T HE ALGORITHM ALLOWS THE USER TO ENTER TWO PRIMARY COLORS AND THEN DISPLAYS THE RESULTING SECONDARY COLOR. T HE COLORS ENTERED BY THE USER WILL BE VALIDATED TO ENSURE THEY ENTERED A PRIMARY COLOR.
