![Problem 2: Time and monetary constraints with options
There are two goods, X and Y, available in arbitrary non-negative quan-
tities (so the consumption set is R²).
Beenish has preferences over consumption bundles that can be represented
by a differentiable, strictly increasing and strictly quasi-concave utility
function u: R2R+, given by
u(2,y) = r®yl-a
where is the quantity of good X, y is the quantity of good Y, and
a € (0, 1) is a preference parameter.
1. Suppose Beenish has 80 AED. In a nearby store (called "Store A"),
the price of good X is p = 2 AED per unit of good X, and the price
of good Y is q = 8 AED per unit of good Y. However, Beenish also
has a time constraint. At Store A, it takes tx = 4 minutes per unit
to purchase good X and ty = 1 minutes per unit to purchase good Y.
That means, purchasing a consumption bundle (x, y) = R² at Store
A would take 4x + y minutes. Beenish has only 80 minutes to do her
shopping.
(a) In an appropriate diagram, illustrate Beenish's constraint set, given
that she has both a monetary constraint and time constraint.
(b) Describe Beenish's demand for good X and her demand for good Y
as a function of her preference parameter a € (0, 1), and illustrate
her demand for good X, i.e., x(a), in an appropriate diagram.
(c) For what values of a does Beenish not spend all of her wealth? For
what values of a does Beenish spend all of her wealth and use up
all of her available time?
2. Now suppose that there is another store (called "Store B"), which is](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0a46b8d2-68f8-4ff5-85d9-0145753bf32f%2F2e2fb545-071b-415d-8350-fb45752548ba%2Fvjz8dpi_processed.jpeg&w=3840&q=75)

2. Now suppose that there is another store (called "Store B"), which is
![further away, where Beenish could do her shopping instead. At Store
B, the goods are half-price: good X only costs 1 AED per unit and
good Y only costs 4 AED per unit. At Store B, it still takes tx = 4
minutes per unit to purchase good X and ty = 1 minutes per unit to
purchase good Y. However, it also takes 40 minutes to drive to Store B
and back, and so Beenish's total time for shopping is only 40 minutes
if she travels to Store B.
(a) In an appropriate diagram, illustrate Beenish's constraint set, given
that she has both a monetary constraint and a time constraint but
now has the option between two stores.

Y as a function of her preference parameter a, and illustrate her
