A monopolistic firm operates in three markets described by the inverse demand
functions
P₁ = 63-4Q1
P2 = 105-5Q2
P3=75-6Q3,
where Q₁ is the quantity sold in market i.
The total cost of this firm is given by C = 20 + 15Q, where Q is the total quantity
produced (Q = Q1 + Q2 + Q3).
1. Write down the optimization problem this firms wants to solve, as an
optimization problem with three variables, Q1, Q2, and Q3..
2. Write down the first order conditions.
3. Find the critical values.
4. Write down the second order condition and check whether they are satisfied.
