Problem 3. b = (36,12), 6 = (18, 48), d = [73b -| (1 t)c] where t = 0.8. 1. Calculate the coordinates of bundle d. 2. Show bundles b, c, and d in a graph. Show the coordinates of each bundle clearly. Problem 4. Draw indifference curves from the following utility functions. Draw at least three indifference curves for each utility function and use arrows to denote the direction of increasing utilities. 1- Way) = my 2. U(5c, y) = a3: + by 3. U($,y) = min(aac, by)
