Question: Suppose the production possibility frontier for guns (x) and butter (y) is given by
x2 + 2y2= 900.
a. Graph this frontier
b. If individuals always prefer consumption bundles in which y = 2x, how much x and y will be produced?
c. At the point described in part (b), what will be the RPT and hence what price ratio will cause production to take place at that point? (This slope should be approximated by considering small changes in x and y around the optimal point.)
d. Show your solution on the figure from part (a).
