Can anyone please help me solve this question? As I am finding it really difficult to answer.

Two companies have investments which pay the following rates of interest: Fixed Float Firm A 6% Libor Firm B 8% Libor+0.5% Assume A prefers a fixed rate and B prefers a floating rate. Show how these two firms can both benefit by entering into a swap agreement. If an intermediary charges both parties equally a 0.1% fee and any benefits are spread equally between Firm A and Firm B, then 1) what rates could A and B receive on their preferred interest rate? 2) Please draw the cash flow chart.|
