Semoga membantu.........2000 A + 4.000 B ≤ 1.600.000→ A + 2 B ≤ 800.....(i)
A = 0 , B = 400
B = 0 , A = 800
A + B ≤ 500 ...(ii)
A= 0 ,B = 500
B = 0, A = 500
titik potong (i) dan (ii)
A+ 2B = 800
A + B = 500...(-)
B = 300
A = 200
(A,B) = (200, 300)
laba untuk daerah HP
(0, 400) , laba = 400x 1.600 = 640.000
(500,0), laba = 500 x 800 = 400.000
(200, 300), laba = 200(800) + 300(1600) = 640.000
laba maksimal = 640.000
dengan 200 unit A dan 300 unit B
atau dengan 400 unit B
Laba (A,B) = 800 A + 1600 B
