Utility maximization under constraint
Lucas gets utility (satisfaction) from two goods, A and B, according to the utility function
U(C, D) = 25[C−3 +4D−3]−4 +25. While Lucas would like to consume as much as possible
he is limited by his income. Maximize Lucas’ utility subject to the budget constraint using

- Assuming the two good case. When a person is attempting to maximize utility and the price of one of the two goods increases, then: a. The budget constraint will expand (rotate away from the origin), shifting the budget line outward indicating fewer choices are now affordable and a lower utility level is now possible. b. The budget constraint will contract (rotate towards the origin), shifting the budget line inward indicating more choices are now affordable and a lower utility level is now possible. c. The budget constraint will contract (rotate towards the origin), shifting the budget line outward indicating fewer more are now affordable and a higher utility level is now possible. d. The budget constraint will contract (rotate towards the origin), shifting the budget line inward indicating fewer choices are now affordable and a lower utility level is now possible.Suppose pizza(P) and hamburger(H) are perfect substitutes for Andy.
