We will be looking at the sensitivity report for changing the RHS of a constraint. a. Which are the binding constraints? Give the names, and justify why you say they are binding constraints. b. If the advertising expenditure increases by $400, does the shadow price change? Explain why or why not. C. If possible, give the change in profit for a $400 increase in advertising expenditure. If you cannot calculate this, explain why it cannot be done. d. If the retail distribution constraint decreases by 75, does the shadow price change? Explain why or why not. e. If possible, give the change in profit for the 75-unit decrease in retail distribution. If it is not possible, explain why not. f. Suppose both changes in b and d occur. Use the 100% rule to determine if the shadow prices change. Be sure to show all your work. 8. If possible, give the total change in profit for the two changes in RHS given above. If it is not possible, explain why it is not possible.
