Stefan sells jin a bicycle for $114 a for $18. the total cost for jin is 120% of what stefan spent or to buy the bike and helmet. how much did stefan spend originally to but a bike and helmet. how much money did he make by selling the bicycle and helmet to jin ?

The selling cost for Stefan bicycle = $114 and

the selling cost of a helmet = $18.

The total cost for Jin is 120% of the money spent.

Let us assume purchasing cost of a bicycle = $x.

Purchasing cost of a halmet = $y.

For bicycle

120% of x is $114  

=>  1.20 × x = 114

Dividing both sides by 1.20, we get

x=$95.

For helmet.

120% of y is $18.

=> 1.20 × y = 18.

Dividing both sides by 1.20, we get

y = $15.

$114 - 95 = $19

$18 - 15 = $3.

you bought 31 v bucks
