There is no question that ZylexA has to be produced, because the company
cannot make ZylexB without starting with ZylexA. The question is, “If you
have a unit of ZylexA, should you take up production time converting it into
ZylexB or should you just make more ZylexA?”
The analysis indicates that production of ZylexB actually yields profit at a
rate of $.265 per minute. Thus, ZylexB should be produced.
