Accounting Project in Excel

I am having a real hard time with this, since I am not an excel function expert. Your help is greatly appreciated. Here are the instructions:

Description
You are the owner of a family practice which also sells fitness equipment and wish to convert the payroll account to an Excel
worksheet, which will automatically calculate gross pay, taxes, healthcare costs, commissions, and net pay for your five employees.

Directions
1. Build a worksheet to calculate the payroll for any week.
For each employee, the worksheet should calculate gross pay, taxes, commission, healthcare, and net pay. All employees work
at least twenty hours per week, with wages ranging from $22.50 to $34.00 per hour. Employees who work more than thirty
hours per week earn overtime pay, calculated at one and one-half times the employee's hourly rate. Employees also receive a
three percent commission for fitness equipment sales greater than $100.

a. Enter a descriptive worksheet title, column titles, and row labels
b. Enter employee names and data required to calculate the items noted below
c. Write formulas and functions to complete the items noted below

2. Given the following guidelines, enter data into the worksheet.
a. There are five employees, each of whom worked at least 20 hours
b. Three of the five employees worked more than 30 hours, with none exceeding 34 hours
c. Two of the five employees are eligible for 3% commission based on fitness equipment sales

3. Write and copy formulas and functions to show:

deducted from gross pay
3. Healthcare deduction (12% of gross pay)

5. Net pay

b. Column totals: gross pay, taxes deducted, healthcare deducted, commission, net pay

6. Save the worksheet in landscape mode.
7. Rename a duplicate copy of your worksheet (remember to add a footer with your name, worksheet name, and date in the
duplicate copy). Using the duplicate copy of the worksheet, select the Display Formulas option, adjust the width of the columns
as needed, and save the worksheet in Landscape mode.
