Discuss with the difference between Change in Quantity Demand and Change in Demand. Part III: work out (5%) 1. The demand for bottled water in a small town is as follows Price per bottle Quantity 1.00 500 1.50 400 2.00 300 2.50 200 3.00 100 Determine 2 a. Calculate the price elasticity of demand for bottled water for a price rise from $1.00 to $1.50? Is demand elastic or inelastic for this price change? b. Calculate the price elasticity of demand for a price rise from $2.50 to $3.00. Is demand elastic or inelastic for this price change? 2. Suppose chaltu is consuming X and Y commodity most of the time. If utility function of a chaltu is given by U=xy. given price of x is 3, price of y is 2 with the income of 300.find a) The utility maximizing level of commodities x, and y. b) The MRSxy at utility maximizing position. c) The maximum utility. 3
