Which ordered pair maximizes the objective function p = 3x + 8y?
(0, 0)
(2, 7)
(5, 6)
(8, 1)

Correct answer is C.

Substitute each of those ordered pairs in until you get the largest number so: (0,0)=3(0)+8(0)=0 

(2,7)=3(2)+8(7)=62 

(5,6)=3(5)+8(6)=63 

(8,1)=3(8)+8(1)=42 

SO the answer would be (5,6)

10 meters because it can't be 1 or 10 cenemiters because that's way too short and 1 meter i ls only 12 inches so thats also too short so it has to be 10 meters
