Your calculation should be wrong. As Mr. Wong need to refund $100 to his neighbour. The calculation should be :
) C/ T$ o0 H, r5 k% K$100 (refund to neighbour from Mr Wong's own money) + $79 (paid to the young man) - $3 (earning from the sale) = $176

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