PF = $4 and PB = $1 and income Y =
$140. Marginal utilities of F and B are:
MUF =
40F-0.2B0.6 and MUB =
30F0.8B-0.4
Graph the budget constraint (with F on the horizontal axis, B
on vertical axis.) Document the intercepts (numerically)
and slope of constraint.
Calculate the utility-maximizing choices of F and
B. Show on your graph.
PF decreases to $2. Find the new
utility-maximizing amount of F; show graphically.
Plot out the demand curve for F.
Explain why we interpret the demand curve as a marginal
value/benefit (i.e., explain the connection between the demand
curve and utility maximizing choices in parts b and c.)
This part is a little tricky: Suppose that this
person is given a gift card worth $20 that can only be used to
purchase (i.e., it can’t be used to purchase any
B). Show how this changes the budget constraint (use
price PF = $2 and PB = $1.
Andre buys two goods, food f and clothing c , with the utility
function U ( f, c ) = f · c + f . His marginal utility of food is M
U f = c + 1 and his marginal utility of clothing is M U c = f . He
has an income of 20. The price of clothing is 4. a. Derive the
equation representing Andre’s demand for food, and draw this demand
curve for prices...
Samantha purchases food (F) and other goods (Y ) with the
utility function U = FY. Her income is 12. The price of a food is 2
and the price of other goods 1. a) How many units of food does she
consume when she maximizes utility? b) The government has recently
completed a study suggesting that, for a healthy diet, every
consumer should consume at least F = 8 units of food. The
government is considering giving a consumer...
Carina buys two goods, food F and clothing C,
with the utility function U = FC + F.
Her marginal utility of food is MUF= C
+ 1 and her marginal utility of clothing is
MUC= F. She has an income of 20. The
price of clothing is 4.
a) Her demand for food is represented by F =
20/PF , where PF is
price for Food. True/False.
b) Calculate the income effects on Carina’s consumption of food
when the...
Suppose a person has utility function, prices, and income:
U(a,B) = 2 ln(A) + ln(B), Pb=1 and m=12. Draw her price offer curve
and explain. Hint: it may be useful to think about the number of
B's she purchases as Pa changes.
1A.) The utility function and the prices are the
following:
U = 40 x1 + 20 x2
P1=4, P2=3 and I =1,200
What is the optimal amount of x1?
1B.) The utility function and the prices are the
following:
U = 3 x1 + 33 x2
P1=37, P2=12 and I =5,004
What is the optimal amount of x2?
14. A person’s utility function for leisure (L) and income (Y)
is U(L, Y) = 10L½ Y½.
This means the person has MUL = 5(Y/L)½
and MUY = 5(L/Y)½
The person has non-labor income of $1000 a month and can earn
$100 per day by working. Assume a month has 30 days and a person
can choose each day whether to work or have leisure.
a) If the person is working 12 days in the month, is the person
maximizing...

Jane's utility function is represented as U=F^0.5C^0.5, F is the
quantity of food and C is the quantity of clothing. If her budget
constraint is represented as 120= 2F +C, her optimal bundle of
consumption should be .... (Please show clearly each mathematical
step. Thank you so much!! I really appreciate it.)
A.(50F, 50C).

A consumer is choosing among bundles of two goods. Their utility
function is u = x1 − x2. They have cashm = 20 and the prices are p1
= 5 and p2 = 4. Sketch their budget set. Indicate their optimal
choice of bundle. Sketch a couple of their indifference curves,
including the one that passes through their optimal choice.
There are two goods – c and p. The
utility function is U (P,C) = P 0.75 C 0.25.
$32 is allocated per week for the two goods, c and p.
The price of p is $ 4.00 each, while the price of c is $ 2.00
each. Solve for the optimal consumption bundle.
Suppose that the price for good p is now $ 2.00 each. Assuming
nothing else changes, what is the new optimal consumption
bundle.
Draw the appropriate...
