Solve the linear programming model formulated in Problem 57 for Tracy McCoy.
a. Are any of the ingredients left over?
b. If Tracy could get more of any ingredient, which should it be? Why?
c. If Tracy could get 6 more eggs, 20 more cups of flour, or 30 more minutes of oven time, which should she choose? Why?
d. The solution values for this problem should logically be integers. If the solution values are not integers, discuss how Tracy should decide how many of each item to bake. How do total sales for this integer solution compare with those in the original, non-integer solution?
