Question

Mencari fungsi penawaran dan permintaan

Answer 1

Fungsi permintaan:
Titik potong (16,0) & (8,10)

(P - P1)/(P2 - P1) = (Q - Q1)/(Q2 - Q1)
(P - 0)/(10 - 0) = (Q - 16)/(8 - 16)
P/10 = (Q - 16)/(-8) (kali 2 kedua ruas)
P/5 = (Q - 16)/(-4)
(-4)(P/5) = Q - 16
Qd = -4/5P + 16

Fungsi penawaran:
Titik potong (0,4) & (8,10)

(P - P1)/(P2 - P1) = (Q - Q1)/(Q2 - Q1)
(P - 4)/(10 - 4) = (Q - 0)/(8 - 0)
(P - 4)/6 = Q/8 (kali 2 kedua ruas)
(P - 4)/3 = Q/4
Qs = 4(P - 4)/3
Qs = 4/3P - 16/3
