Answer to Question #176006 in Microeconomics for Bbbbnb

Question

Suppose a particular consumer has 8 birr to be spent on two goods, A and B. The unit price of good A is 2 birr and the unit price of B is 1 birr. The marginal utility (MU) she gets from consumption of the goods is given below.

Quantity

1 36 30

2 24 22

3 20 16

4 18 12

5 16 10

6 10 4

A) Based on the cardinal analysis, what is the combination of the two goods that gives maximum utility to the consumer?

B) What is the total utility at the utility maximization level?

Answer 1

A. The utility is maximized when $MUA/PA = MUB/PB$ and

$PA×QA + PB×QB = 8.$

Both equities are true if QA = 2 units and QB = 4 units.

B. The total utility at the utility maximization level is:

TU = (36 + 24) + (30 + 22 + 16 + 12) = 140 units.
