Answer to Question 1

Tris buys 4 pairs of pants and 4 belts because this is the combination that allocates (spends) all of his budget and has the marginal utility per dollar from a pair of pants equal to the marginal utility per dollar from a belt. For the first requirement, that Tris allocate his entire budget, the combination of 4 pants and 4 belts spends (4 pairs of pants)  (20 per pair of pants) = 80 on pants and (4 belts)  (5 per belt) = 20 on belts, for a total spent of 100. For the second requirement, the equality of the marginal utilities per dollar, the marginal utility per dollar from a pair of pants is (100 units)  (20 ) = 5 units per dollar and the marginal utility per dollar from a belt is (25 units)  (5 ) = 5 units per dollar.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
