Frankly, I think the best way is not to add up the whole career because it's a pain in the neck. You're just looking at differentials, so you should assume that the corporate drone job is zero and freeze it at that, then calculate the relative costs and benefits of the Peace Corps gig and see if it adds to more than zero or less than zero. That's the way they worded the problem.
