I think the general case (with the independence and constant marginal cost-effectiveness assumptions) will be harder to follow for some readers (and not easier to follow for anyone), much more work for me (I’m not sure how I would approach it yet), and not general enough to be very useful. Even more generally, it’s a multi-objective linear program, which we would solve algorithmically, not symbolically for a closed form solution.
Re algebra, are you defending the numbers you gave as reasonable? Otherwise, if we’re just making up numbers, might as well do the general case.
