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

$ 12

Step-by-step explanation:

First, we'll find out how much, in total Jin spent.

    114 (bicycle) + 18 (helmet) = $ 132

Now, we know she spent 110% of what Stefan did.

    132 = 110% of x (the value stefan spent)

So, we want to get x, the cost, by itself. We will divide 110.

    132/110(%) = x

Remember, percent is a decimal that's been moved (2 places to the right), so... (we move it 2 places to the left for a decimal)

    132/1.10 = 120

Stafen originally spent $120 on the equipment. Now we subtract this amount from what Jin spent:

    132 - 120 = 12

Stefan made $12 off of Jin's purchase.

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
