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<=
7 Set + num ENDO Display total (Points : 10)
4. 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 then 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
5. is: green” EndIf End (Points : 10)

pseudocode and explain whether one is more important to develop than
the other. (Points : 10)
8. (TCO 1, 2, 3, 4, & 5) Compare and contrast sequence control
structures and selection control structures. (Points : 10)
