An electronics firm carries out a small-scale test launch of a new low-priced pocket calculator. It estimates from this test that if it went into full-scale production it would sell between 1,000 and 2,500 calculators per month, and that its monthly revenue in thousands of shillings over this range of sales could be represented by the equation:
R = - x2 + 5x
Where: x is the monthly output in thousands of calculators (it is assumed that it sells its entire output).
From experience of calculator production, the firm estimates its marginal cost in thousands of shillings
could be represented by the equation:
MC = x2– x + 2
and that its fixed costs will be Sh.500 per month.
Required:
i) Determine the average cost and revenue equations for this firm.
ii) Determine the profit-maximizing output, the price that should be charged to maximize profit, and how
much each calculator will then cost to make.

where x represents time in months. The project can run for eleven months at most.
Required:
i) Determine the initial cost of the project.
ii) Calculate the break-even time in months for the project.
iii) Determine the best time to end the project.
iv) Determine the total profit within the break-even points

Gatheru and Kabiru Certified Public Accountants have recently started to give business advise to their
clients. Acting as consultants, they have estimated the demand curve of a clients firm to be;
AR=200-8Q
Where AR is average revenue in millions of shillings and Q is the output in units.
Investigation of the client firm‟s cost profile shows that marginal cost (MC) is given by:
MC=Q2-28Q+211(In million shillings)
Further investigations have shown that the firm‟s cost when not producing output is sh.10 million.
Required:
i) The equation of total cost
ii) The equation of total revenue
iii) An expression for profit.
iv) The level of output that maximizes profit
v) The equation of marginal revenue.

Two CPA students were discussing the relationship between average cost and total cost. One student said
that since average cost is obtained by dividing the cost function by the number of units Q, it follows that the derivative of the average cost is the same as marginal cost, since the derivative of Q is 1.
Required:
Comment on this analysis.

Demand function for a firm is given by
P=12 - 0.4Q
P is the price of the product, Q is the quantity demanded, and the total cost (C) is given by
C = 5 + 4Q + 0.6Q2
At what price and quantity will the firm have maximum profit? If the firm aims at maximizing sales, what
price should it charge?
