As you remember, in the Product Mix Case in Chapter $3$ discussed during the lecture, we realized it is not profitable to produce the Holiday Mix. That being said, we make $5000$ pounds of the Holiday mix since there is an order of $5000$ pounds for this mix. Let's assume there are no customer orders received for the three mixes, so we can freely choose the optimal order size for each mix. Right now the profit contribution per pound is $$2\mathrm{.}25$ for the Holiday Mix. What should be the profit contribution per pound for the Holiday Mix, so that it becomes profitable to produce the Holiday Mix?
