After he bought the 成本为18元的物品,
he would have 1,000 - 18 = 982;

After he got changes from 邻居家,
he had 1082 + 100 = 1,082;

Then he gave 客户 79, so he got 1082 - 79 = 1,003

After 店主 compensated his 邻居,
he should have 1,003 - 100 = 903

So he lost 1,000 - 903 = 97

But 店主 was supposed to make profit 3,
so in total he lost 97 + 3 = 100
