Question

Stefan sells Jin a bicycle for ​$116 and a helmet for ​$16. 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?

Answer 1

He originally spent 120$

He made 12 extra dollars.

Explanation:

To solve this I turned the 110% into a decimal.

So I divided 110 by 100 and got 1.1

In order to find the original number you would then need to divide the total cost of the bicycle and helmet together by 1.1

So, 116 + 16 = 132

132/1.1= 120

Hope this helps
