Answer:
the that minimizes the function is (80, 50) for which C = 9050
Explanation:
(0, 160). (55, 70). (80, 50). (170, 0)..... available pairs missing out in the question
Step 1: to get the pair that minimizes the objective function C = 60x + 85y, we plug in each pair and work out the minimum value of C.
(0, 160): C = (60*0) + (85*160) = 13600
(55, 70): C = (60*55 + (85*70) = 9250
(80, 50): C = (60*80) + (85*50) = 9050
(170, 0): C = (60*170) + (85*0) = 10200
Hence the minimum value of C occur at (80, 50)
