Question

Diketahui fungsi permintaan Qd = -2P + 20 dan fungsi penawaran Qs = 4P - 10, maka titik keseimbangannya adalah??

Answer 1

QD = QS
-2P + 20 = 4P - 10
-2P - 4P = -10 - 20
-6P = -30
-P = -30 / 6
-P = -5
P = 5

Q = -2P + 20
Q = -2(5) + 20
Q = -10 + 20
Q = 10

Keseimbangan Harga
(Q,P)
(10,5)
