Answer:
Look below
Explanation:
Let's first find how much Jin paid for the bicycle and the helmet:
$163+$17=$180
Now we find what Stefan originally paid for the bicycle and the helmet by using x as the original price:
150%x=180
150/100(x)=180
Simplify the fraction:
3/2(x)=180
x=180*2/3
x=120
Now we find how much he made:
180-120=60
Stefan originally spent $120 and made $60 selling the bicycle and helmet to Jin.
