Suppose that the final cost per die in the example in Section 2.3.2 is constrained to be no greater.

Suppose that the final cost per die in the
example in Section 2.3.2 is constrained to be no greater than $0.094. The only
parameter you can adjust is the material cost of step L. In this case the
material cost can be lowered to any value (the tradeoff is the reliability of
the product, which is outside the scope of this problem). What material cost of
step L should you select?
