Demand (Chapter 6 in the book)
Problem 1. Chad's utility function is $U(x_p,x_c) = x_px_c$, where $x_p$ is protein shakes in
gallons and $x_c$ is chicken breasts in pounds. We want to find Chad's demand function for
protein shakes $x_p(p_p,p_c, m)$ and for chicken breasts $x_c(p_p,p_c,m)$, where $p_p$ - price of a gallon
of protein shape, $p_c$ - price of a pound of chicken breasts, and $m$ - Chad's income.

$p_px_p + p_cx_c = m$
(b) Write the slope of Chad's indifference curve at point $(x_p,x_c)$
$\MRS = -\frac{p_c}{p_p}$
(c) Chad's indifference curve is tangent to his budget constraint at point $(x_p,x_c)$ if the
following condition is satisfied:
$p_px_p + p_cx_c = m$  $\MRS = -\frac{p_c}{p_p}$
(d) Given the equation in (c) and Chad's budget constraint, what is Chad's demand
function for protein shakes $x_p(p_p,p_c,m)$?
(e) Given the equation in (c) and Chad's budget constraint, what is Chad's demand
function for chicken breasts $x_c(p_p,p_c,m)$?
f) What fraction of income does Chad spend on protein shakes?
g) What fraction of income does Chad spend on chicken breasts?
h) Is protein shake a normal good for Chad?
i) Is chicken breast an inferior good for Chad?

a. Find Mac's demand functions. b. Find Mac's utility as a function of prices and income. What is his utility if Pc=10, Pr=20, I=200? c. Find Mac's utility if the price of CDs rises to Pc=12.50. d. How much money would you have to give Mac to make him just as happy as before the price change? Draw the picture of the relevant budget constraints and indifference curves. e. Imagine instead that the price change has not happened yet. How much money would you have to take away from Mac to give the same change in utility that the price change would give? Draw the picture of the relevant budget constraints and indifference curves.

00:01 So, first one, mac demand function for cds depend on price p c d and his income i.
00:23 It can be written as q c d equals d p c d i.
00:31 In b 1, to find mac utility function of price and income, we need specific utility function.
01:01 Assume that it is u x y equals x to the power 0 .5 into y to the power 0 .5.
01:11 So, c to find the utility when p c d equals to 10, p y equals to 20 and i equals to 200.
01:20 So, u 10 200 p c d equals to 10.
01:22 So, p c d 10 to the power 0 .5 into 200, 0 .5.
01:29 So, on solving this, we get 14 .14...
