consider a consumer who wants to choose between optimal bundles (x ,y) and who faces Px = 5, Py= 5, and I= 40.

a.) Find the optimal bundle (x^,y^) when MUx= 16x and MUy= 20y.

b.) Find the optimal bundle (x^,y^) when MUx= 18x and MUy = 20y.

c.) Describe what happens to incentivize a change in optimal bundles from part a.) to part b.).

d.) Plot the x and x points you found in parts a.) and b.) in a single graph. The graphshould have P x on the vertical axis, and x on the horizontal axis.

e.) On the same graph, draw demand at these two points. Make sure that both x and x are clearly part of some demand curve or curves.
