I'm not able to follow your work. You should really consider using an online drawing canvas to write your work. Using a number 2 pencil and loose leaf paper is something of last century.

Hero · Answer

Besides that, I don't follow your methods of calculating derivatives. They don't seem to make any sense.

Ballery1 · Answer

i made a silly mistake at the beginning of the solution. since i was solving for the revenue...i forgot to multiply the price function by x since R(x) = x.P(x) but yeah i got help and we fixed it. thanks though :)
