Use the following to answer questions 11-14:
Suppose that firms A, B, C and D are Bertrand duopolists in the salt industry. The market demand curve can be specified as Q=100-3p, Q=qA+qB+qC+qD.
(The firms choose prices simultaneously.)
The cost to firm A is C(qA)=7qA.
The cost to firm B is C(qB)=3qB.
The cost to firm C is C(qC)=7qC
The cost to firm C is C(qD)=3qD
Firm A will earn? (piA=?)
Firm B will earn? (piB=?)
Firm C will earn? (piC=?)
Firm D will earn? (piD=?)
