Week 2 iLab
TCO 2: Given a simple problem, design a solution algorithm that uses arithmetic expressions and built-in functions.
Scenario
Your goal is to solve the following simple programming exercise. You have been contracted by a local antique store to design an algorithm determining the total purchases and sales tax. According to the store owner, the user will need to see the subtotal, the sales tax amount, and the total purchase amount. A customer is purchasing four items from the antique store. Design an algorithm where the user will enter the price of each of the four items. The algorithm will determine the subtotal, the sales tax, and the total purchase amount. Assume the sales tax is 7%.
Be sure to think about the logic and design first (IPO chart, flowchart, and pseudocode). Display all output using currency formatting.
Advanced (optional): Use a constant for the 7% sales tax.

1—Variable List With Data Type
List all variables you will use (use valid variable names). Indicate whether the data type is string, integer, or decimal, and so on.
2—IPO Model
List the inputs, any processes/calculations, and outputs. Use the same valid variable names you used in Step 1.
Inputs Process (calculations) Outputs
3—Flowchart
Use MS Visio to create a flowchart. Paste flowchart here, or attach as separate document. Use the same valid variable names you used in Step 1.
4—Pseudocode or VB Code
Describe your solution using pseudocode or actual Visual Basic code. Use the same valid variable names you selected in Step 1.
5—Desk-Check
Desk-check your solution by selecting appropriate test data.
Test data: List the values for your test data.
Expected output: What is the expected output of your program?
For each variable in your program, write the variable name selected in Step 1, in the heading for the variable columns (not all columns may be used).
For each step in your algorithm, write its step number in the left column (not all rows may be used).
Using the sample inputs above, enter the value of each variable after each step has been executed. Note any output displayed to the user.
