HELP IT'S REALLY EASY
The profit depends on the amount x that you charge for a box. The equation p= -0.5x^2 + 25x - 150 models the profit. What's the smallest amount that can be charged to make a profit of at least $125?

p= -0.5x^2 + 25x - 150
seek smallest value of x such that p>=125
does that make sense?

You want -0.5x^2 + 25x - 150 >=125.
Solve the quadratic inequality and eliminate extraneous solutions.

0.5x^2 + 25x - 150 >=125
x^2+50x-300>=250
(x^2+50x+625)>=550+625
(x+25)^2>=1175
