Step-by-step explanation:
The given objective function is [tex]C = 60x + 85y[/tex]
To check that which ordered pair is minimizing the objective function-we will substitute all the ordered pair one by one in the given function and we will calculate the value of C. The ordered pair which will give the minimum value will be the answer.
For (0, 160)
[tex]C=60\times 0+85\times 160=13600[/tex]
For (55, 70)
[tex]C=60\times 55+85\times 70=9250[/tex]
For (80, 50)
[tex]C=60\times 80+85\times 50=9050[/tex]
For (80, 50)
[tex]C=60\times 170+85\times 0=10200[/tex]
Hence the ordered pair which minimizes the objective function is (80, 50)
