Stefan sells Jin a bicycle for $103 and a helmet for $18. The total cost for Jin is 110% 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?

$110

Step-by-step explanation:

If 110% = $103 + $18

110% = $ 121

Then 100% = ?

(100 ÷ 110) × 121 = $110

Amount Stefan spent = $103 + 18

= $121

Amount Jin made = $121 - 110

= $11
