Aggregation of Labor Supply

As a financial analyst in charge of assessing workforce dynamics, I am examining a market with num firms banks. Out of these, num a banks utilize a labor supply function detailed by supply function a, whereas num b banks employ a labor supply function given by supply function b. Here P is the hourly wage in dollars, each function gives the hours of labor supplied per week to a single member of its group, and no worker supplies labor to more than one of them. With a prevailing wage of $price per hour, how much labor is collectively offered by the employees in this banking sector? Round to two decimals.
