Final answer:
In a perfectly competitive market, Doggies Paradise Inc. calculates its total revenue, marginal revenue, total cost, and marginal cost for different output levels to determine the profit-maximizing quantity, which occurs where marginal revenue equals marginal cost.
Step-by-step explanation:
When we talk about pricing in the context of a perfectly competitive firm, we are often referring to the ability of the firm to efficiently allocate resources to maximize profit given the market conditions. Doggies Paradise Inc., a hypothetical company that sells winter coats for dogs, operates within such a market structure. In analyzing their costs and revenues, we focus on concepts like total revenue, marginal revenue, total cost, and marginal cost. These metrics are crucial for understanding how many units the company should produce to maximize profit.
For instance, if Doggies Paradise Inc. sells each dog coat for $72 and has varying total variable costs ranging from $64 to $270 depending on the number of units, we can calculate their total revenue and marginal revenue by multiplying the number of units sold by the price. Total cost is calculated by adding fixed costs to the total variable costs at each level of output. Marginal cost, which is the cost of producing an additional unit, is calculated by taking the change in total variable costs when an additional unit is produced.
The profit-maximizing quantity is where marginal revenue equals marginal cost, as producing beyond this point would not add to profits and might even decrease them. This concept is fundamental in microeconomic theory and applies widely in business decision-making contexts.
