Revenue Derivations from Price and Quantity

Steps:

• Price (P) equals average revenue (AR) per unit sold, as AR = total revenue / quantity.
• Total revenue (TR) = P × quantity (Q), directly calculable from given data.
• Costs are unknown, so average cost, profit, or total profit cannot be determined.
• Thus, only AR and TR are derivable without additional information.

Why D is correct:

• By definition, AR = P and TR = P × Q, both solely from price and quantity.

Why the others are wrong:

• A: Average cost and profit require cost data, which is absent.
• B: Average cost needs cost information; total revenue is derivable but irrelevant here.
• C: Total profit requires subtracting costs from revenue; average revenue is derivable but insufficient alone.

Final answer: D
