Answer:
Stefan originally spent $110
Stefen made $33 by selling the bicycle and helmet to jin.
Step-by-step explanation:
let ,
the original cost of bicycle and helmet for Stefan be 'x'
now,
total cost for Jin of bicycle and helmet = 126 + 17
= 143
also, total cost for Jin = 130% of original cost for Stefan
⇒ 143 = [tex](\frac{130}{100} )x[/tex]
⇒ x = 110.
hence,
profit made by Stefan = total cost for Jin - original cost for Stefan
= 143 - 110
= 33
