Asalesperson receives a 2.5% commission on sales, what commission does the salesperson receive for $8,000 in sales

Percentage of commission received by the salesperson = 2.5%
Amount of sales made by the salesperson = $8000
Then
The amount of commission received by the salesperson = (2.5/100) * 8000 dollars
                                                                                             = 2.5 * 80 dollars
                                                                                             = 200 dollars
So the salesperson receives a commission of $200 on the total sales made. I hope the procedure is clear enough for you to understand. You can use this method in future for solving similar problems without requiring any help from outside.
