Yes, your answer is correct, but is only the 1st part, u forgot he paid back another $100 to his neighbor, that is another $100, not related to the first $100, you really have to 想清楚

dun forget that guy, not only the $18 dollars product he got on hand, he also got $79 dollars on this hand, he paid a fake 100 dollars bill, it means he paid nothing, and the boss gets nothing too, so u need to add 79 dollars to the total.
