If the salesperson receives a 2% commision on the sale price (which I am assuming) first you want to calculate the sale price.
Total price - 15% * total price
so
275 - (.15*275)
233.75 is the sale price.
Then take two percent of that
233.75 * .02 = $4.675
They make $4.68 (If rounded to the nearest cent.)
