Consider the following utility function, which specifies Matt's preferences over two goods, grapes (G) and strawberries (S). (Please note that we call this type of utility function quasilinear.)
U(G, S) = 4G + 16S^(1/2)
(a) (5) What is the marginal utility of G? What is the marginal utility of S?
(b) (5) What is the slope of the indifference curves at S = 1 ?
