3. Suppose a consumer has preferences over two goods that can be represented by the quasi-linear utility function U(x, y) = 2vxty 2\\x+ y. The marginal utilities are MUx = 1/Vx and MUy = 1. (1) (557 ) Is the assumption that more is better satisfied for both goods? (2) (53 ) Does the marginal utility of x diminish, remain constant, or increase as the consumer buys more x? Explain. (3) (63)) What is the expression for MRSxY? H
