David is assigned to the project, and S is the number of hours Sarah is assigned to the project.) MinL+S+D=110 s.t. Minimum Lisa Minimum Sarah Maximum Lisa Maximum Sarah Total Time L,D,S0 (b) How many hours should be assigned to each graphic designer? \begin{tabular}{l|l} Lisa's Hours & hours \\ David's Hours & hours \\ Sarah's Hours & hours \\ What is the total cost (in dollars)? \\ $ \end{tabular} (c) Suppose Lisa could be assigned more than 50 hours. What effect would this have on the optimal solution? Explain. Since the constraint is , additional hours for Lisa change the solution. (d) If the minimum number of work hours on the project were higher, would the optimal solution change? Explain. Since the constraint is , assigning more hours to the project change the solution.
