P1 = 10.000 P2 = 12.500 Q1 = 450 Q2 = 400 Tentukan Fungsi Permintaan!

Jawaban:

P = -50Q + 32500

Penjelasan dengan langkah-langkah:

(P-P2)/(P1-P2) = (Q-Q2)/(Q1-Q2)

(P-12500)/(10000-12500) = (Q-400)/(450-400)

(P-12500)/(-2500) = (Q-400)/(50)

P – 12500 = (Q-400)/(50) × (-2500)

P – 12500 = -50Q + 20000

P = -50Q + 20000 + 12500

P = -50Q + 32500
