a. Find the maximum production level.
b. How many units of labour are needed at that point.
c. Obtain the function of marginal product of labour (MRL ).
d. Graph the production function and the (MRL .
3. A firm has the following demand function and the average cost

Q
- Find the profit function.
b. Estimate the marginal cost function.
c. Obtain the production that maximizes the profit.
d. Evaluate the average cost and the marginal cost at the maximising
production level.
4. A firm has the following total cost function TC =100q-5q²+ 0.5q³ (10 points).
- Find the average cost function.
5. Considering the following supply and demand equations (20 Points):
Qs = 3P – 1

dP = 0.5(Qd – Qs )
dt
- Find the expressions. P(t), Qs (t) and Qd (t). When P (0) = 1 , is the system stable or unstable?
b) If the constant for the change of excess of demand changes to 0.6, this is:
dP= 0.6(Qd−Qs )
