P2 = Rp 85.000,- Q2 = 7.750 buah
Dit : Fungsi permintaan ?
a
P = 20Q - 70.000
b
Q = 1/20 P - 3.500
c
Q = 20P + 3.500
d
Q = 1/20P + 70.000
e
P = 20Q + 3.500
P2 = Rp 85.000,- Q2 = 7.750 buah

P = a+bQ
65.000 = a + 6.750b
85.000 = a + 7.750b
__________________ - (eliminasi )
- 20.000 = - 1.000 b
-20.000 / -1.000 = b
20 = b
65.000 = a + 6.750(20)
65.000 = a + 135.000
65.000 - 135.000 = a
- 70.000 = a
jadi
P = 20Q -70.000 (A)
