(TCO 2) The first module is usually considered to be called the_____ module. (Points : 4)1. (TCO 10) A retail store is having a customer appreciation sale.Depending on the total dollars purchased, the customer could receive adiscount on his or her total purchases. You are to develop pseudocodethat will obtain the total dollars purchased from the user, determine thediscount percentage, and display the total amount due. When thepurchases are more than $100, the discount is 10%. When the purchasesare $100 or less, the discount is 5%. (Points : 10)2. (TCO 10) A small business in your neighborhood would like anapplication developed that determines the average dollar amount spentfor every three purchases. The user will enter three different purchaseamounts. You need to display the average to your client. Complete thepseudocode to design your logic. (Points : 10)3. (TCO 9 & 10) There is a logic error in the following pseudocode. Theloop needs to execute four times. What statement(s) would you need toadd or change to correct the logic? Be sure to explain why you areadding or changing the statements.
 Set 
 REPEAT
 Set +
  • 4. 1
 UNTIL total < 7
 EndWhile
 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 countyidentifying code. Counties with a number less than 10 have a 6% salestax. The 11–25 codes have a sales tax of 7%. Codes above 25 have asales tax of 8%. The code is entered by the user. 
 Begin
 DeclareReal salesTax
 Declare _____ countyCode
 _____ “Enter the countycode: “
 _____ countyCode
 If _____ <= 10 then
 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 countdown.
 Begin
 Declare_____ count
 Set 
 REPEAT
 Display “countdown: “ +_____
 Set - 1
 UNTIL _____
 EndDo
 Display “LIFTOFF!”
 End (Points : 10)6. (TCO 4, 5 & 10) Complete the pseudocode by rewriting thealgorithm. The colors red, blue, and yellow are known as primary colorsbecause they cannot be made by mixing other colors. When you mix twoprimary colors, you get a secondary color. Mixing yellow and blue getsyou green. Mixing red and blue gets you purple. The algorithm allowsthe user to enter two primary colors and then displays the resultingsecondary color. The colors entered by the user will be validated toensure they entered a 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”

 Set control1 = “y”
 ENDO
 Set control2 =“n”
 DOWHILE control2 = “n”
 If (color2 <> “yellow”) _____(color2 <> “red”) _____ (color2 <> “blue”) then
 Prompt “secondprimary 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
  • 5. (_____) then
 Display “secondary color is: green”
 EndIf 
 End(Points : 10)7. (TCO 1, 2, 3, & 4) Describe the difference between a flowchart andpseudocode and explain whether one is more important to develop thanthe other. (Points : 10)8.
