a. The marginal utility of the fourth unit of Y is__________.

b. The marginal utility of the fifth unit of X is___________.

c. The marginal utility per dollar spent on the third unit of X is__________.

d. The marginal utility per dollar spent on the second unit of Y is__________.

e. If the consumer has $420 to spend, ______ unit of X and _______units of Y maximize utility subject to the budget constraint. Explain.

f. If the consumer has $220 to spend, _______ units of X and_______ units of Y maximize utility subject to the budget constraint. Explain.

g. If the consumer wanted 4 units of X and 6 units of Y, what would have to be his/her budget constraint in order to maximize his/her utility? Explain.
