There are two goods, apples and bananas. The price of apples is PA = $2, and the price of bananas is Pp = $3. A consumer has $120 to spend, and his utility function is U(A, B) = 2A-BS. With apples on the x axis, the slope of the budget line is At A=2, B=1, the marginal utility of A is and the marginal utility of B is v At the optimal bundle, the consumer buys apples and v bananas
