(TCOs 2, 3, 8) Your program will read in a tax rate as a percentage (i.e., input 8 for 8%) and the prices of three items. The program is to calculate the total price (before tax) of the items, the tax payable on those items (using the specified tax rate), and the total amount of the sale including tax. Print the total price (before tax), the amount of tax, and the total amount of the sale as output

(TCOs 3, 4, 8) PART 1 (10 points): A department store is having a customer appreciation sale. Depending on the total dollars purchased, the customer could receive a discount on his or her total purchases. You are to develop pseudocode that will obtain the total dollars purchased from the user, determine the discount percentage, 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%.

(TCOs 4, 5, 8) Write a program to input a purchase amount and calculate the sales tax and total due. The sales tax depends on the county identifying code. Counties with a number less than 10 have a 6% sales tax. The 11–25 codes have a sales tax of 7%. Codes above 25 have a sales tax of 8%. The purchase amount and county code are entered by the user. Use a loop to validate that the county code is between 1 and 30. Display the amount of the sales tax and the total

(TCOs 5, 8) Write a Visual Basic loop that counts up from 5 to 100 by 5s

(TCOs 5, 6, 8) Review the following scenario and complete the design:
Scenario
You have been asked by the Payroll department to create a program that will calculate the weekly pay for the company’s 30 employees. The employee names and pay will be stored in arrays. The program will prompt the user to provide each employee’s full name, hourly pay rate, and hours worked. The program will then ask whether the employee is single or married. If an employee is married, the tax rate is 25%; if he or she is single, the tax rate is 20%. Also, if the employee worked more than 40 hours in a week, the number of hours greater than 40 is paid a rate 1.5 times the pay rate.
After all data are input and calculated, the program will display a payroll report with a list of all the employee names and weekly pay. In addition, the program will display the total payroll for the week and the average weekly pay.

Write a program using Visual Basic, prompt the user for the appropriate input, and display the output as described above. You may assume all data are valid. Provide a program introduction message that tells the user how to use the program
