We have that the student gains the same reward completing any one of the three programs; thus the program with the least cost is optimal. We have that the first program costs 38.600$. Nevertheless, we need to also account for the lost opportunity, which is 2000$ per month. Thus, instead of going to the program, the student could have saved 38.600$+6*2000$=50.600$. Now for the 12month program, we have similarly 35.000$+12*2000$=59.000$. Finally, for the 15month program, the calculation yields: 28.600$+15*2000$=58.600$. We see that the best program to attend is the 6-month one (lowest total opportunity cost); despite it being the most expensive one, after completing it the student can make up for it by grabbing the other opportunity and making 2000$ per month (in the other programs, the student cannot work for 6 or 9 months more than this program).
