5. The table provides data on income and demand for good X and Y. Period Income P, Qu P, Q, 1 $10,000 $25 10 $1042 2 10,000 28 9 10 40 3 10,000 28 8 15 35 - 11,000 28 9 15 36 5 11,500 34 7 20 32 A. Calculate the following elasticities using arc formulas: (1) price elasticity of demand for X (i1) price elasticity of demand for Y (111) 1ncome elasticity for X (1v) income elasticity for Y (v) cross elasticity of demand for Y with respect to the price of X (vi) cross elasticity of demand for X with respect to the price of Y B. Why should no elasticities be calculated between periods 4 and 5
