a. Draw below and find the Feasible Zone (FZ) for the following equations: K ≤ 20; L ≤ 50; and 5K + 2L ≥ 100. Make sure to mark the FZ with letters A, B, C, D, etc.

b. Then, Min 5K + 2L; what will be the optimal solution? Why? 

c. If you were given: Max 5K + 2L, what will be the optimal solution? Why? 

d. Then, Min 4K + 2L; what will be the optimal solution? Why? 

e. If you were given: Min 5K + L, what will be the optimal solution? Why?
