Final answer:
The correct answer is that the line of business is profitable, with total revenues exceeding total costs, resulting in a profit of $35,000 after accounting for both fixed and incremental costs.
Step-by-step explanation:
The correct answer is option A: this line of business is profitable. To determine profitability, we must calculate total revenue and subtract both fixed and variable costs. The revenue generated from commercial patients is 3,000 patients × $75 = $225,000.
Revenue from HMO members is 1,000 members × $60 = $60,000. Thus, the total revenue equals $285,000. The total variable costs (incremental costs) are ($50 × 3,000) + ($50 × 1,000) = $200,000.
Subtracting the variable costs and the fixed costs of $50,000 from the total revenue yields a profit of $35,000. Options B and C are incorrect because they both suggest actions that would lead to a reduction in the number of patients and therefore a potential reduction in profits without providing enough information to quantitatively support those actions.
To determine whether a line of business is profitable, we can calculate the contribution margin. The contribution margin equals the selling price minus the variable costs.
For the commercial patients, the contribution margin is $75 - $50 = $25. For the HMO members, the contribution margin is $60 - $50 = $10. Since both contribution margins are positive, it indicates that the line of business is profitable.
