l. Martha's utility function is L" = BC: where B = bananas per week and C = coconuts per we ek . Find M'Uls and MUc. 1illhat is her marginal rate of substitution if bananas are on the vertical axis and coconuts on the horizontal axis? Martha's income is $121], the price of a banana is 32, and that of a coconut is $1. Find the number of bananas and coconuts she will consume to maximize her utility. Illustrate your answers in a graph. Say the price of a banana increases to 33. 11what is the new optimal bundle? Illustrate your answers on the same graph. In a related graph= derive her demand curve for bananas with price on the vertical axis= and show the points on the demand curve corresponding to the before- and afterprice- increase equilibria. 2. For the following: please answer "True" or "False": and in each case, explain your answer with the help of a diagram. a. b. Unlike indifference curves, isoquants can intersect. If inputs into production cannot be substituted for each other but l_:1_a_y_e__t_o be employed in fixed proportions, isoquants are straight, downward-sloping lines. The "Law of Diminishing Marginal Returns" could also be termed the "Law of increasing Marginal Costs." Shortrun costs are never equal or lower than longrun cost
