This means that the sales alone would bring him

#38,000color(red)(cancel(color(black)("$ sales"))) * "$17.5"/(100color(red)(cancel(color(black)("$ sales")))) = $6,460#

If you take into account his salary, the distributor's total earnings will amount to

#"earnings" = $28,000 + $6,460 = color(green)($34,460)#
