Transcribed Image Text:3. The functions determining weekly supply and demand of a product are as
follows:
TC = 6,404,000 – 1,240Q + 0.155Q2
Q = 64,000 – 5OP
TC = total costs of production (US$)
Q = quantity demanded of product
P = price per unit of product (US$)
where:
a) i) Determine the Marginal Cost function.
ii) Derive the Total Revenue and Marginal Revenue functions.
iii) Determine the profit maximising price and quantity and hence the
maximum profit.
b) Calculate the own-price elasticity of demand if the output is 10,000 units
per week and explain your answer.
