Your calculation should be wrong. As Mr. Wong need to refund $100 to his neighbour. The calculation should be :
# i- Y" q% c9 Y9 Gtvb now,tvbnow,bttvb$100 (refund to neighbour from Mr Wong's own money) + $79 (paid to the young man) - $3 (earning from the sale) = $1765.39.217.76: k! @, v# H0 K4 [/ C# _9 x( t) C0 g
This should be the fact.

Sorry, I think wrong. Actual loss should be $118 (refund to neighbour $100 + cost of gift $18) - $21 (sales income) = $97
