Final answer:
Total revenue is the income generated by a business, but to determine the true financial performance, profit must be considered by subtracting the total cost.
Step-by-step explanation:
Total revenue is the income generated by a business from selling its products. It is calculated by multiplying the price of the product by the quantity of output sold. In this case, it refers to the amount of money the pharmacy is making from the sale of its items.
However, when considering profit, it is important to take into account all costs incurred by the business, not just the cost of the items sold. Profit is calculated by subtracting the total cost from the total revenue.
Therefore, the answer to your question is b. Profit because it considers all costs and provides a more accurate measure of the pharmacy's financial performance.
