Solving Quadratic Inequalities

Hello,

I can't understand how to solve this problem:

Nathan is a product manager for a home security company.  Through testing and focus groups, he has modeled the equation P = -(x - 32)2 + 1000 to represent the profit (in thousands) of the price x for a new home security camera.  Find the prices in dollars at which Nathan can make a profit of at least $471, 000.  Show your work as it is done in the lesson content and include units of measurement..  HINT:  Use 471 as part of the inequality you set up, not 471,000.

Re: Solving Quadratic Inequalities

hi Jade,

I've seen this twice recently.  Have a look back through old posts in Help Me from the last few days.
