Final answer:
To find the profit-maximizing quantity for AAA Aquarium Co., financial metrics like total revenue, marginal revenue, total cost, and marginal cost are calculated for each output level. Diagrams depicting total revenue and total cost, along with marginal revenue and marginal cost, guide in determining the quantity where MR=MC, indicating maximum profit.
Step-by-step explanation:
The AAA Aquarium Co. problem involves calculating various financial metrics to determine the profit-maximizing quantity of output for a firm. To solve this, one needs to tabulate the total revenue, marginal revenue, total cost, and marginal cost for each output level from one to five units. Based on these calculations, diagrams of the total revenue and total cost curves, as well as the marginal revenue and marginal cost curves, are drawn to visually represent the relationships and help identify the profit-maximizing output level.
The profit-maximizing quantity is determined where marginal revenue equals marginal cost (MR = MC). The output level that satisfies this criterion will yield the maximum profit for the firm. If marginal revenue exceeds marginal cost, the firm can increase profit by increasing output. Conversely, if marginal cost is greater than marginal revenue, decreasing output will prevent losses.
