Verified step by step guidance
1
Step 1: Understand the definition of profit in microeconomics. Profit is the difference between the total revenue a firm earns from selling its goods or services and the total cost incurred in producing those goods or services.
Step 2: Recall the formula for total revenue (TR), which is the price per unit multiplied by the quantity sold: \(TR = P \times Q\).
Step 3: Recall the formula for total cost (TC), which includes all costs of production, both fixed and variable.
Step 4: Write the profit equation by subtracting total cost from total revenue: \(\text{Profit} = TR - TC\).
Step 5: Compare the given options with the profit formula. The correct representation is \(\text{Profit} = \text{Total Revenue} - \text{Total Cost}\).
