Step-by-step explanation:

First step)

200= -1000x^2 + 1100x -2.5⇒ -1000x^2+1100x-2,5-200 = 0, ⇒-1000x^2 +110x-202,5 = 0

3. the point  where the profit is highest is in he vertex of the parable for x = b/2a

x = - 1100/2(-1000) = 1100 /2000= 0,55, for this value the x, thah represent the price highest  for a profit at least of $ 200
