Suppose there is a fourth drug, drug D, that Repco can
produce and sell. Each unit of drug D requires 4 labor hours, 1 unit of drug A,
and 1 unit of drug C to produce, and it sells for $150 per unit. Modify the
current model to incorporate drug D and reoptimize. If drug D isn’t produced in
the optimal solution, use sensitivity analysis to see how much higher its
selling price would have to be before Repco would produce it. If drug D is
produced in the optimal solution, use sensitivity analysis to see how much
lower its selling price would have to be before Repco would stop producing it.
