QUESTION TWO 2
[25 MARKS]
You have a choice to make between clothing (C) and food (F), the price of cloth is N$45.00
per cloth and the price of food is N$30.00 per kg. Your utility function is U(F, C) = zo{Fc
and your income is N$30000.00.
a) If the price of food increases from N$30.00 to N$40.00 while the price of cloth and income
remain the same, construct demand curve for food. Use a clear labelled graph to present
your answer. Let food be on the x-axis.
[12.5 marks]
b) If the price of cloth increases from N$45 to N$55.00 while the price of food and income of
consumer remain the same N$30 and N$30000.00 respectively, construct demand curve
for cloth. Use a clear labelled graph to present your answer. Let food be on the x-axis.

QUESTION FOUR
[25 MARKS]
Consumers derived utility from consuming good x and good y. Utility function is UX,Y) =
20x0-4yo.4 good y is a composite good (Py= N$1}, the price of good x is (Px =N$10.00) and
consumer income is (I= N$S00}. Government would like to increase the consumption of good
x with 60 per cent. Government can achieve this objective by either giving cash subsidy or a
voucher that can only be used in the purchasing of good x. Government can only spend
N$300.00.
a) Use a well labelled graph to represent the above information.
[S marks]
b) Calculate optimal combination of good x and goody associated with each option. Which
option will you recommend and why?
[10 marks]
c) If government has only N$200.00 to spend to increase the consumption of good x,-which
option will you recommend?
[10 marks]
