Consider the following set of cost equations for each firm in a perfectly competitive market:

Let x represents units of output

Marginal Cost = 4x + 6

Average Total Cost = 2x + 6 + (24 / x)

Suppose the market price is equal to \$18

Determine the level of profit-maximizing output for the firm in this market. (1 Mark)

4. Consider the following set of cost equations for each firm in a perfectly competitive market:

Let x represents units of output

Marginal Cost = 4x + 6

Average Total Cost = 2x + 6 + (24 / x)

Suppose the market price is equal to \$18

Suppose also that the market demand is given by the equation: Price = -x + 48

Suppose now that some firms exit the market and the new market price is equal to \$22

Calculate the new level of profit-maximizing output for each firm in this market. (1 Mark)

Suppose the market price is equal to \$18

Suppose also that the market demand is given by the equation: Price = -x + 48

Suppose now that some firms exit the market and the new market price is equal to \$22

Is this market now in long-run equilibrium? (1 Mark)
