The following shows the demands and marginal revenue in two markets (D1 and MR1, and D2 and MR2) for a price discriminating firm along with total demand, DT, marginal revenue, MRT, and marginal cost MC.

D1 = 700 - 0.2Q

D2 = 540 - 0.2Q

MRT = 620 - 0.2Q

DT = 620 - 0.1Q

MC = 0.0006Q^2 - 0.55Q + 279

How much total output should the firm produce (for both markets combined)? How should that output be allocated between markets 1 and 2? What price should the firm charge in each market?
