Suppose a firm sells two goods, Good A and Good B. Use the following information to answer the questions that follow: Profit maximizing price of Good A = R200 Profit maximizing price of Good B = R75 MC at Q* of Good A = R120 Total revenue of Good A = R26000 Total revenue of Good B = R24000 Rothschild index of Good B = 0.4 Price elasticity of the market demand for Good B = -2 2.1. Calculate each of the following: Ed of Good A =_____________ Ed of Good B =____________ MC at Q* of Good B = R______________ 2.2 Suppose that the firm noticed that when it increased the price of Good A from R200 to R300, the sales of Good B decreased from 1000 to 600 units. Calculate and classify the cross-price elasticity of demand between Good A and Good B. Ec = ________________ Good A and Good B are classified as (substitutes/compliments) 2.3. Use the elasticity coefficient calculated above and the information provided, to calculate by how much the firm's total combined revenue will change if it decreases the price of Good A by 3%? Change in combined total revenue = R_______________ 2.4 Suppose the firm is currently selling 320 units of Good B. Calculate the change in the quantity demanded (in both percentage and in units), if the firm decreases the price of Good A by 3%. Percentage change in Qd =______________________ Change in units__________________
