purchases are more than $100, the discount is 10%. When the purchases
are $100 or less, the discount is 5%. (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: “ _____ countyCode If _____ <= 7 then Set Else If

_____ Display “Done!” End (Points : 10)
6. (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
