Your calculation should be wrong. As Mr. Wong need to refund $100 to his neighbour. The calculation should be :
/ I) }) @0 R3 }5 P* }- u8 z$ i$100 (refund to neighbour from Mr Wong's own money) + $79 (paid to the young man) - $3 (earning from the sale) = $176
$ j* z, D/ t1 x3 r2 C) G( P5.39.217.76This should be the fact.
