The weekly demand for Kelewele among the 2018 batch of MBA students at
UPSA is Qdx =900–10Px +0.2I+5Py –4Pz

Where Qdx is the quantity demanded of Kelewele,

Px is the price of Kelewele per lb,

I is the consumer income in Ghana Cedis,

Py and Pz are the prices of two goods that are related to Kelewele.

a) Based on the demand function above, is

d) What is the equation of the demand curve if consumer incomes are
GHȼ 40, the price of good Y is GHȼ 20 and the price of good Z is
GHȼ 27? 1 Mark

e) Graph the demand function for Kelewele from d)

Now suppose the weekly supply function for Kelewele at UPSA campus

is QSx = -260 + 10Px – 2Pi

Where QSx is the quantity supplied of Kelewele and Pi is the price of
inputs used in preparing Kelewele.

f) What is the supply function if input prices are GHȼ 20?

g) Graph the supply curve from f)
