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. Begin Declare Real salesTax Declare ____ countyCode _____ “Enter the county code: “ Input _____________ If _______ <= 7=""> Set Else If ______ AND ______ then ______________ Else Set 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 countdown. Begin Declare _______ count Set REPEAT Display “countdown: “ + _______ Set - 1 UNTIL ___________ Display “LIFT OFF!” End (Points : 10) 6. (TCO 4, 5 & 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. The colors entered by the user will be validated to ensure they entered a primary color. Begin Declare String color1 Declare String color2 Declare String control1 Declare String control2 ______ “Enter first primary color: “ Input _______ Prompt “Enter the second primary color: “ Input _________ Set control1 = “n” DOWHILE control1 = “n” If (color1 <> “yellow”) ______ (color1 <> “red”) _______ (color1 <> “blue”) then Prompt “first primary color is invalid” Input _________ Else Set control1 = “y” ENDO Set control2 = “n” DOWHILE control2 = “n” If (color2 <> “yellow”) ______ (color2 <> “red”) _______ (color2 <> “blue”) then Prompt “second primary color is invalid” Input color2
Else Set control2 = “y” ENDO If (color1 = “red”) AND (__________) then Display “secondary color is: purple” EndIf If (color1 = “yellow”) AND (_________) then Display “secondary color is: green” EndIf End (Points : 10) 7.
