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. When the purchases are more than $100, the discount is 10%. When the purchases are $100 or less, the discount is 5%. (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.

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. Begin Declare Real salesTax Declare _____ countyCode _____ “Enter the county code: “ _____ countyCode If _____ <= 7=""> Set Else If _____ AND _____ then Set Else _____ EndIf _____


Display “the sales tax is: “ + _____ End (Points : 10) 5. (TCO 5 & 10) Complete the pseudocode by rewriting the algorithm. The design is to display a 60-second counter.

(TCO 4 & 10) Complete the pseudocode by rewriting the algorithm. The colors red, blue, and yellow are known as primary colors because they cannot be made by mixing other colors. When you mix two primary colors, you get a secondary color. Mixing yellow and blue gets you green. Mixing red and blue gets you purple. The algorithm allows the user to enter two primary colors and then displays the resulting secondary color. Begin Declare _____ color1 Declare _____ color2 _____ “Enter first primary color: “ Input _____ Prompt “Enter the second primary color: “ Input _____ If (_____) AND (_____) then Display “secondary color is: purple” EndIf If (_____) AND (_____) then Display “secondary color is: green” _____ End (Points : 10) 7.
