# The function of the population’s demand for a product is Qd = 18-2P, and the supply function for this product

The function of the population’s demand for a product is Qd = 18-2P, and the supply function for this product is Qs = 2P + 2. Suppose the government has set a fixed price for this product at 7 rubles. Draw a conclusion about the economic consequences of this decision.

Qs = 2 × P +2

Qd = 18 – 2 × P

The government has set a fixed price

P1 = 7

Substitute a fixed price into the supply function

Qd = 18 – 2 × 7 = 4

Substitute a fixed price into the demand function

Qs = 2 × 7 +2 = 16

Determine the size of the surplus

Qs – Qd = 16 – 4 = 12

Conclusion: after the state fixed the price at a level above the equilibrium level, then the supply of this good in the market began to exceed the volume of demand. In other words, the market is faced with a surplus of 12 in magnitude.
