3. The manager of a company has determined that the cost function for the production can be described by C = 3Q? + 10Q + 450 where Q is the output each month. If the demand function for any month is Pd = 400 - 2Q, where Pa is the price in £. (а) Determine the following: (i) Revenue function, R (ii) marginal cost function, MC (iii) Average cost function, AC (b) Determine the profit function, P. Hence, find the (i) level of output that would maximise the profit. (ii) maximum profit. (c) Find the marginal average profit function.

Answer question 8(b)
The manager of a company has determined that the cost
function for the production can be described by
8.
C = 3Q? + 10Q + 450
where Q is the output each month.
If the demand function for any month is Pd = 400 – 2Q, where
Pa is the price in £.
(а)
Determine the following:
(i) Revenue function, R
(ii) marginal cost function, MC
(iii) Average cost function, AC
(b)
Determine the profit function, P.
Hence, find the
(i)
level of output that would maximise the profit.
(ii)
maximum profit.
(c)
Find the marginal average profit function.
(d)
Find the value of output when C = P.
(e) Sketch the cost and profit function for Q > 0 on a same
diagram. Show clearly all points of significance.
