You can put this solution on YOUR website!
Let x= the first percentage (applied to 100000)
Let y = the second percentage (applied to the difference between the sales and 100000)
If one salesperson earned $8500 on sales of $175000
then

and another sales person earned $14,800 on sales of $280,000
then

Then 2 equations are:

doing 1st eq by -1

adding both equations we have:
105000y=6300
then y=0.06 (6%)

then

then x=0.04 (4%)

Answer: 1st percentage is 4% and the second is 6%
