A. (10:50)
B. (20:30)
C. (30:20)
D. (50:10)
E. (60:60)

Answer 1

Verified answer

Pd (10,40) dan (20,30)
a = (30 - 40)/(20 - 10)
a = -1

b = P - aQ
b =40 - (-1)(10)
b = 40 + 10
b = 50

⇒Pd = -Q + 50

Ps (10,0) dan (20,10)
a = (10 - 0)/(20 - 10)
a = 1

b = 0 - (1)(10)
b = -10

⇒Ps = Q - 10

↓
Syarat keseimbangan
Pd = Ps
-Q + 50 = Q -10
2Q = 60
Q = 30

P = -30 + 50
P = 20

→Maka output keseimbangan = 30 dan harga keseimbangan = 20
