20 ! your local bakery sells more bagels when it reduces prices, but then its profit changes. the function y = -1000x^2 + 1100x -2.5 models the bakery’s daily profit in dollars from selling bagels, where x is the price of a bagel in dollars. what is the highest price the bakery can charge, in dollars, and make a profit of at least $200?

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

after simplifying it i got: -36.25 as my answer. hope that !
