Answer: Stefan spent 110 dollars on the bike and sold it for 160%. Add 160+16 to get 176. Then multiply 176 by 1.6 (Decimal Form of the precent) To get 110 which is what he spent on the bike originally. Subtract 110 from 160 to get 50 or the profit stefan made from selling the bike. Hope this helps.
Cheers,
