The demand and supply of some good are as follows:
Qd = 2,000 - 30P
Qs = 1,000 + 20P

Suppose that the government supports a price of $30 per unit. The quantity supplied and demanded at this price would be:

A) Qd = 1,700, Qs = 1,700
B) Qd = 2,000, Qs = 1,700
C) Qd = 1,700, Qs = 2,000
D) Qd = 2,000, Qs = 2,000
