Explanation:
A.) Answer to question A is attached.
B.) The price of the pie is $10 according to the question. Please note that in a competitive market, a firm produces that level of output at which price equals MC. I.e P = MC. Where there is no such output, then it will produce up to the level in which P>MC.
Therefore, price(P) is equal to MC, P = MC up to the production of 5 pies.
So, producers in the market = 300 ÷ 5
= 60.
Profit = ( 5 × 10 ) - ( 5 × 7.8 )
= 50 - 39
= $11
Therefore, at a price of $10, 300 pies are sold in the market. Each producers makes 5 pies, so there are 60 producers in the market, each making a profit of $11.
C.) In a competitive market, and in the long run, price = minimum ATC.
Here, the minimum ATC is $7, but the price is $10.
The above means that the market is not in the long run equilibrium because price (P) is not equal to the minimum ATC. Thus in the long run, more firms will enter the market until the price equals ATC.
D.) Producers operating = 600 ÷ 2
= 300
It therefore means that in the long run, each producer earns a profit of $0. The market price is $7, while at this price, 600 pies are sold in the market, and each producer makes 2 pies , hence there are 300 producers in operation.

During a period the demand for the goods by the consumers is called quantity demanded. In the market, 300 producers are operating.
What is marginal cost?
Marginal cost is the additional cost when the additional unit of the goods or services is added.
The table for the total and the average cost is attached in the image below.
Given, the price of the pie is $10 and the price is equal to the marginal cost of the 5 pies produced. The producers in the market are calculated as:
[tex]\rm Producers = \dfrac{300}{5} = 60[/tex]
Profit is calculated as:
[tex]\begin{aligned} & = ( 5 \times 10 ) - ( 5 \times 7.8 )\\\\&= 50 - 39\\\\&= \$11\end{aligned}[/tex]
In the long-run market, the minimum ATC is $7 but the actual price is $10, hence the market will not be in the long run and more firms and corporations will enter the market till the price equilibrates the ATC.
Pie producers in the market is calculated as:
[tex]\dfrac{600}{2} = 300[/tex]
When the market price is $ 7 then the market sold 600 pies while each producer makes two pies hence 300 producers are operating in the market.
Therefore, producers operating in the market are 300.
