Stefan spend originally $110 and the money stefan make by selling the bicycle and helmet to jin is $22 .

Step-by-step explanation:

As given

Stefan sells jin a bicycle for $114 and a helmet for $18.

Total cost of the bicycle and helmet = $114 + $18

                                                            = $132

The total cost for jin is 120% of what stefan spent originally to buy the bike and helmet.

120% is written in the decimal form.

= 1.20

Let us assume that the Stefan spend originally for bike and helmets be x.

Than the equation becomes

1.20 × x = 132

1.20x = 132

x = $110

Therefore stefan spend originally be  $110 .

Now find out how much money did he make by selling the bicycle and helmet to jin .

Money make by Stefan = Total selling cost of helmet and bicycle  - Total amount of  stefan spends for purchasing.

Money make by Stefan = 132  - 110

Money make by Stefan = $22

Therefore the money stefan make by selling the bicycle and helmet to jin is $22 .
