2. (15) Suppose the price of X is $3 per tmit and the price Y is $5 per unit. 9 6 3 2 IJA 5 10 x a. b. The diagram indicates that you have three different income levels. Suppose you buy 4 units of X with IA, 3 mits with 1B, 2 units uith Ic. Calculate three income levels (IA, 1B, and Ic) and units of Y (Y A, YB, and Yc) in each optimal bundle. Given the indifference curve and budget constraint diagram above, constmct Engel curces, one for Good X and another for Good Y. Mark three points on each Engel curve. (label each axis carefully) Engel curve for Good X Engel curve for Good Y
