Ok, I got the same answer, but basically by using the 'fixed formula' for the type of question we had which we were told in class.

I just want to know HOW i would solve this using the inequalities so that I know I can really do this without memorizing a formula...if that makes sense. Please can you show me how to solve this?

]]>Are those the last of the constraints?

With those I can get a maximum of

when

]]>Without even talking about a possible method of solution I am having a problem right there. I am getting no maximum with those constraints. Have you copied the problem exactly?

]]>Is this the problem?

Please check the constraints carefully!

]]>How can I solve this? Thanks bobbym

]]>Looks like a linear programming problem. Have you studied them yet?

2. 2P3 + 5P4 > (4/3)P3 + 6P4.....so P4 < (2/3)P3

PLEASE help me solve this. How do I do it? What do you get? Help help help!
