50 hours available to work on this project. Hourly wage rates are $30 for Lisa, $25 for David, and $18 for Sarah. and S is the number of hours Sarah is assigned to the project.) Min s.t. Minimum Lisa Minimum Sarah Maximum Lisa Maximum Sarah Total Time L,D,S≥0 (b) How many hours should be assigned to each graphic designer? Lisa's Hours David's Hours hours Sarah's Hours What is the total cost (in dollars)? $ (c) Suppose Lisa could be assigned more than 50 hours. What effect would this have on the optimal solution? Explain. The shadow price for this constraint is ∣ , since the constraint is Therefore, additional hours for Lisa change the solution. (d) If Sarah were not required to work a minimum number of hours on this project, would the optimal solution change? Explain. The shadow price for this constraint is since the constraint is - Therefore, assigning fewer hours to Sarah change the solution.
