The demand function for goods has the form Ol = -5p + 25. The sentence function is Qs = 9p-3.

The demand function for goods has the form Ol = -5p + 25. The sentence function is Qs = 9p-3. Find manufacturers’ revenue in a market equilibrium.

The condition for market equilibrium is the equality of supply and demand, that is:

Qd = Qs.

Let us equate the supply and demand functions, calculate the equilibrium price:

-5P + 25 = 9P – 3,

– 14P = – 28,

P = 2.

Substitute the value of the equilibrium price, define the equilibrium volume of sales:

-5 * 2 + 25 = 9 * 2 – 3,

15 = 15.

Let’s find the producers’ revenue under the given conditions:

W = P * Q = 2 * 15 = 30.

Answer: the revenue of producers in a market equilibrium will amount to 30 units.
