Final answer:
To calculate net pay, multiply the number of hours worked by the hourly rate, calculate 5% of total sales, add these two amounts for total earnings, and subtract taxes to find the net pay. Without tax rates, the exact net pay cannot be determined.
Step-by-step explanation:
To calculate your net pay, we need to take into account both your hourly earnings and the commission from the sales you made. First, let's determine your base pay from your hourly work. If you work 41 hours this week and suppose your job pays a certain hourly rate, you simply multiply the number of hours worked by your hourly rate to get the base pay.
Next, you also receive a 5% commission on the sales you made. Since you sold $4,000 of goods this week, your sales commission is calculated as 5% of $4,000. Use the percentage formula to determine this amount, which is the product of the total sales and the commission rate.
Lastly, add your base pay to your commission to get the total earnings before taxes. However, to find your net pay, you'll need to subtract taxes from this amount. The money you have left when your paycheck makes its way to you and all of the required taxes are taken out is what we consider your net pay. Without the specific tax rates or amounts, we can't calculate the exact net pay, but this is the process you would follow to determine it.
