Please help me find values for open slot and simplify the process to get to the answers as much as possible.

Assume that two companies (A and B) are duopolists who produce identical products. Demand for the products is given by the following linear demand function: P=400QAQB where QA and Q3, are the quantities sold by the respective rms and P is the selling price. The total cost functions for the two companies are T6,, = 1,500 +110QA + QAZ TCB = 1,200 + 4093 + 299 Assume that the rms act independently as in the Cournot model (i.e., each firm assumes that the other firm's output will not change). For Company A, the long-run equilibrium output is and the selling price is $ For Company B, the long-run equilibrium output is , and the selling price is . At the equilibrium output, Company A earns total prots of and Company B earns total prots of . Therefore, the total industry profits are
