PAJAKQS = 36-3PQD =2P -4 T = 3​

Jawaban:

QD=QS

2P-4=36-3P

2P+3P=36+4

5P= 40

PE= 8 (HARGA PAJAK)

Q=2p-4

p=8->Q=2.8-4

QE= 12 (jumlah barang)

sesudah di kenai pajak

Q=36-3P

3P= Q-36

P=1/3Q-6

dikenai pajak 3/unit

P=1/3Q-6+3

P=1/3Q-3

1/3Q=p+3

Q=3p+9

syarat keseimbangan

QD'=QS'

2P-4=3P+9

2P-3P=9+4

-P= 13

PE'=-13

Q=2p-4

p=-13-> Q=2.(-13) -4

QE'= -26-4=-30
