a. carilah fungsi penawaran nya berdasarkan fungsi penawaran tersebut tentukan berapa bilah harga 100 2.diketahui fungsi permintaan xd=40-p fungsi penawaran 4p-

1. a. Fungsi penawaran
P1 = 100
Q1 = 5

P2 = 150
Q2 = 10

P = a + bQ

100 = a + 5b
150 = a + 10b
____________ -
-50 = -5b
-50/-5 = b
10 = b

100 = a + 5(10)
100 = a + 50
100 - 50 = a
50 = a

Ps = 50 + 10Q

jika P = 100. Q = ?

Ps = 50 +10Q
100 = 50 + 10Q
100 - 50 = 10Q
50 = 10Q
50/10 = Q
5 = Q


2. Qd = 40 - P
Qs = 4P - 50

Keseimbangan Pasar /ME
Qd = Qs
40 - P = 4P - 50
90 = 5P
90/5 = P
18 = P

Q = 40 - P
= 40 - 18
= 22

ME pada harga 18 SMU jumlah 22 unit
