Question

Jack maximizes her utility when she buys 6 pumpkins and 4 caramel apples. If the price of pumpkins is $4 each, and the price of caramel apples is $2 each, which of the following must also be true when he is maximizing her utility? Assume the quantity of pumpkins is measured on the x axis, and the quantity of caramel apples is measured on the y axis.

Options:

A. Jack's income is $28

B. Jack's marginal rate of substitution is 2

C.The slope of Jack's indifference curve is -0.5

D. The slope of Jack's budget line is 2

Answer #2

Option A is incorrect because at a utility maximizing point, consumer spend all her income. Total income = Price of pumpkin * Quantity of pumpkin consumed + Price of caramel apple * Quantity of caramel apple consumed = $4 * 6 + $2 * 4 = $32

Option B is incorrect because marginal rate of substitution (slope of indifference) is calculated as (marginal utility from pumpkin / marginal utility from caramel apple) which is not given here.

Option C is incorrect because marginal rate of substitution / slope of indifference curve is calculated as (marginal utility from pumpkin / marginal utility from caramel apple) which is not given here.

**Option D is correct** as Slope of a budget is
calculated as: Price of pumpkin (Good on Y axis) / Price of caramel
apple (Good on Y axis) = (4 / 2) = 2.

Jack maximizes her utility when he buys 6 pumpkins and 4 caramel
apples. If the price of pumpkins is $4 each, and the price of
caramel apples is $2 each, which of the following must also be true
when he is maximizing her utility? Assume the quantity of pumpkins
is measured on the x axis, and the quantity of caramel apples is
measured on the y axis.

Suppose when the price of Apples is $13, the price of Bananas is
$15, and the budget is $390. If Apples are on the x-axis and
Bananas are on the y-axis, what is the slope of the Indifference
Curve at the Utility Maximizing point?

3. Nora enjoys fish (F) and chips(C). Her utility function is
U(C, F) = 2CF. Her income is B per month. The price of fish is
PF and the price of chips is PC. Place fish
on the horizontal axis and chips on the vertical axis in the
diagrams involving indifference curves and budget lines.

George is making a consumption choice over apples (a) and
bananas (b). George’s preferences are represented by u (a, b)
=(2a^2)b where a > 0 and b > 0. Denote by f = (a, b) a fruit
bundle.
1. In terms of preference relations, how does George rank the
three bundles f1 = (3, 1), f2 = (1, 3), and f3 = (2, 2) relative to
each other?
2. State George’s marginal rate of substitution (MRS) function,
MRS(a, b) (where...

Imagine that you are moving to a new city after you graduate to
start a job. You are deciding how much of your paycheck to use for
housing (call this H) and how much to save for other spending (call
this S). Your utility function is U ( H , S ) = H 0.5 ⋅ S. Housing
is measured in square feet, and the cost per square foot is p h.
Saving is measured in terms of dollars and...

Grandma lives in the forest and relies on her favorite niece,
Red, to do her weekly grocery shopping. Grandma consumes only two
goods, bread and wine, and each week she spends $120 on them. In
week 1, price of bread is $2 per loaf and price of wine is $4 per
bottle. Knowing perfectly well Grandma's preferences, and willing
to make her grandma as well off as possible, Red buys 10 bottles of
wine.
