Final answer:
To find the profit-maximizing quantity for Doggies Paradise Inc., total revenue, marginal revenue, total cost, and marginal cost must be calculated for one to five units.
Step-by-step explanation:
Cost Analysis and Profit Maximization
A perfectly competitive firm, Doggies Paradise Inc., sells dog winter coats for $72 each. To determine the profit maximizing quantity, we must analyze total revenue, marginal revenue, total cost, and marginal cost for each output level from one to five units.
First, we calculate the total revenue by multiplying the number of units sold by the price, which is 72 dollars per dog coat. Marginal revenue in a perfectly competitive market is equal to the price of the good, so it remains $72 for each additional unit sold.
Total cost is the sum of fixed costs and variable costs at each level of production. Marginal cost is the additional cost incurred by producing one more unit.
To find the profit-maximizing quantity, we should keep producing units until the marginal cost equals the marginal revenue. If the marginal cost exceeds the marginal revenue, it means producing the additional unit would result in a loss; hence, production should stop before this point.
Based on the figures provided, to calculate the profit or losses, we subtract the total cost from the total revenue at each level of output. Once the table is created and analyzed, we can graph the total revenue and total cost curves, and marginal revenue and marginal cost curves to visually ascertain the profit-maximizing quantity where the marginal revenue and marginal cost intersect.
