Which ordered pair minimizes the objective function cap c is equal to 60 x plus 85 y ?

Substitute each ordered pair into the objective function, 60x + 85y. For (80, 50), the value is 60(80) + 85(50) = 4,800 + 4,250 = 9,050. This is less than the values for the other choices, so (80, 50) minimizes the objective function.
