We warned you about clearing denominators in the quality constraints. This problem indicates what happens if you don’t do so.

a. Implement the quality constraints as indicated in inequality (4.3) of the text. Then run Solver with Assume Linear Model checked. What happens? What if you uncheck the Assume Linear Model option?

b. Repeat part a, but increase the selling price of heating oil to $40 per barrel. What happens now? Does it matter whether you check or uncheck the Assume Linear Model option? Why?
