First, we need to find the quantity Q by setting the two price functions equal to each other:

20 = 8 - 4Q
4Q = 12
Q = 3

Now that we have the quantity, we can find the total revenue (TR), total cost (TC), and profit (П).

TR = P Q
TR = 20 3
TR = 60

TC = 49 + Q + Q^2
TC = 49 + 3 + 3^2
TC = 49 + 3 + 9
TC = 61

П = TR - TC
П = 60 - 61
П = -1

Therefore, the total revenue is 60, total cost is 61, and the profit is -1. This means that the firm is operating at a loss.
