MR = $ What is marginal cost when quantity is 15 ? MC = $ If this firm is a monopoly, at what quantity will marginal profit be $0.00? quantity = If this is a perfectly competitive market, which quantity will be produced? quantity = Comparing monopoly to perfect competition, which of the statements are true? Select all that apply. The monopoly's price is higher. The monopoly is likely to be less responsive to consumers. The perfectly competitive market's ouput is lower.

Check the explanation

Explanation:

Marginal revenue is the revenue earned by selling an additional unit of output. Marginal Revenue for fifteenth unit of output is calculated as below.

Marginal Revenue= =

Marginal Cost is the additional cost incurred on producing additional unit of output. Marginal Cost for fifteenth unit is calculated as below.

Marginal Cost=

The marginal revenue when the quantity is 25 is

The marginal Cost when the quantity is 15 is

The marginal profit of a monopoly is 0 when the marginal profit is equal to the marginal cost. The monopoly produces at an output where the marginal profit is equal to zero.

Thus, the output produced by the monopoly is

The corresponding price set is at $70.

120 units  

A perfectly competitive market produces an output where the marginal cost is equal to

the average revenue. Thus a competitive firm produces

The corresponding price is set at $50.

130 units)

The monopoly price $70 is higher than the competitive firm's price $50.

Hence, the correct option is
