Pro Gary and Maja are the only people in town who drink cashew milk (c). The other good they both consume is avocado (a). Gary's utility function is UGary = 3ca, so his marginal utility functions are MUc = 3a and MUa = 3c. Maja's utility function is UMaja = 3c + 24a, so her marginal utility functions are MUc = 3 and MUa = 12/a . They each have $200 to spend. (a) On separate graphs, plot Maja and Gary's demand curves for cashew milk, assuming the price of avocados is constant at $2. (b) Find the equation for the aggregate demand curve for cashew milk and plot it, keeping the price of avocados constant at $2.
