Stefan sells jin a bicycle for $160 and a helmet for $16. the total cost for jin is 160% of what stefan spent originally to buy the bike and helmet. how much did stefan spend originally? how much money did he make by selling the bicycle and helmet to jin?

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,
