Ginger's utility function is \(U(x,y) = x^{2}y\) .Prices are Px=8 and Py=2 and Income is I=240.
a)Determine Ginger's optimal basket given these prices and her income.
b)If Py increases to 8 and Ginger's income is unchanged, what must the Px fall to in order for her to be exactly as well off as before the change in Py. (hint: solve for the total utility in a) and then keep that constant to solve for the new Px)
