If the inverse supply and inverse demand functions of a commodity X are given by Pₛ = 8 + 4X and P_d = 20 - 5X respectively, and if price P and quantity X are determined at the equality of total demand and total supply, then the total surplus = consumer's surplus + producer's surplus is equal to (A) approximately 4 units. (B) 8 units. (C) 18 units. (D) 72 units.
Also written as: If the inverse supply and inverse demand functions of a commodity X are given by P_s = 8 + 4X and P_d = 20 - 5X respectively, and if price P and quantity X are determined at the equality of total demand and total supply, then the total surplus = consumer's surplus + producer's surplus is equal to
