A lawyer has two clients. She charges a yearly retainer plus a separate fee for each consultation. The retainer is a fee each client pays just to secure the services of the lawyer for the following year and the consultation fee is the price the lawyer charges to do one legal job for the client. The client's annual demand curves for legal jobs are

Client 1: Q₁=22-P Client 2: Q₂=19-2P

where P is the consultation fee in thousands of dollars for one legal job and Q₁ is the number of legal jobs done for client i.

The lawyer's marginal cost for completing one legal job is 2.2 (also in thousands of dollars).

The lawyer wants to determine the fee schedule (retainer and consultation fee) that will maximize her profit. She feels she cannot use a different fee schedule for each client, so she must set one retainer and one consultation fee that apply to both clients.

She should charge a consultation fee of $_________ thousand per legal job. (enter response rounded to two decimal places).
