No, But should I charge $24 to get the largest weekly profit?
*November 25, 2007*

**Calc**

So is it -3(p-24)(p+4) I have to find which will give me my largest profit so I need to set them equal to zero. That would then be $24, right? How do I determine max possible weekly profit?
*November 25, 2007*

**Calc**

Wait, the other one is wrong, it is -3(p-24)(p-4). So the max possible weekly profit is $24 dollars??? Now how do I determine the max possible weekly profit and be certain the profit is maximized?

That is wrong too Now I got -3p^2+84p-288 Is this right, I cannot figure out how to factor it though
*November 25, 2007*

**Calc**

I made a mistake it should be -296 but I do not think this is right because I know I am supposed to factor this and I cannot get it to factor.
