which ordered pair minimizes the objective function c = 60x + 85y?\n(0, 160)\n(55, 70)\n(80, 50)\n(170, 0)

Explanation:

Step1: Substitute (0, 160)

$C = 60\times0+85\times160=0 + 13600=13600$

Step2: Substitute (55, 70)

$C=60\times55 + 85\times70=3300+5950 = 9250$

Step3: Substitute (80, 50)

$C=60\times80+85\times50=4800 + 4250=9050$

Step4: Substitute (170, 0)

$C=60\times170+85\times0=10200+0 = 10200$

Answer:

(80, 50)
