asically,opportunity cost equals the sum of true cost and the benefit of the second best choice.
For example,in the first case,your true cost is just the transportation cost and the entry fees for skiing.However,your opportunity is higher,because you would have earned some cash if you had gone for the part-time job.So your opportunity cost equals the sum of the salary of the part-time job and the true cost.
In the second case,your second best choice is to study in the library.You don't lose anything for not doing that.So your opportunity cost equals your true cost under this situation.
