Permintaan P1 = 2 P2 = 5 Q1 = 12 Q2 = 0 Tentukan Fungsi Permintaan (Qd)

Permintaan
P1 = 2
P2 = 5
Q1 = 12
Q2 = 0
Tentukan Fungsi Permintaan (Qd)

Jawaban:

Qd = 20 – 4P

Penjelasan:

$frac{q - q1}{q2 - q1} = frac{p - p1}{p2 - p1} \ frac{q - 12}{0 - 12} = frac{p - 2}{5 - 2} \ frac{q - 12}{ - 12} = frac{p - 2}{3}$

3 (Q – 12) = -12 (P – 2)

3Q – 36 = -12P + 24

3Q = 36 + 24 – 12P

3Q = 60 – 12P

$q = frac{60 - 12p}{3}$

Q = 20 – 4P

Fungsi permintaan Qd = 20 – 4P✔
