Answer:
a) $ 120
b) $ 53
Step-by-step explanation:
Cost of Bicycle paid by Jin = $173
Cost of Helmet = $ 19
Total amount paid by Jin = $173 + $19 = $192
This amount is 160% of what Stefan originally spent. Let the amount he originally spent was n, so we can write:
192 = 160% of n
192 = 1.6n
n = [tex]\frac{192}{1.6} = 120[/tex]
Thus, Stefan originally spent $120 for buying the bicycle and the helmet.
Profit which he made from this sale = $ 173 - $ 120 = $53
So he made $53 by selling Jin a bicycle and a helmet
