Stefan sells Jin a bicycle for $149 and a helmet for $19. The total cost for Jin is 140 % 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?

the answer is 510

375 + 75 = 450

450 + 60 = 510
