Opportunity cost is the loss due to forgoing one opportunity to select another one alternative.
In this case, the forgone alternative is the full-time employment and other expenses for the term when the alternative chosen is to be in school.

The part-time amount earned while at school is subtracted as it would be compensated be during full time employment.
Therefore;
Opportunity cost = $20,000+$10,000+$1,000-$8,000 = $23,000
