Question

Edgar Anderson earns $300 a week plus a 15% commission on all sales over $1,000. If Mr. Anderson's sales for one week are $2,500, what is his gross pay for that week? 

Answer 1

Basic amount that Edgar Anderson earns per week = $300
Sales of Mr. Anderson for one week = $2500
Percentage of commission on sales above $1000 = 15%
Then
Amount of commission
earned for the week = [2500 - 1000] * (15/100) dollars
                                 = 1500 * (15/100) dollars
                                 = 15 * 15 dollars
                                 = 225 dollars
Then
Gross pay of Edgar Anderson for the week = (300 + 225) dollars
                                                                     = 525 dollars
So the gross pay of Edgar Anderson for the week is $525.
