Solve the linear programming model formulated in Problem 25 for Rucklehouse Public Relations by using the computer.
a. If the firm could reduce the minimum interview requirement for either telephone or personal interviews, which should the firm select? How much would a reduction of one interview in the requirement you selected reduce total cost? Solve the model again, using the computer, with the reduction of this one interview in the constraint requirement to verify your answer.
b. Identify the sensitivity ranges for the cost of a personal interview and the number of total interviews required.
