anonymous · Answer

okay,i ask you later..
thanks you..=)

anonymous · Answer

Take the derivative of of profit, set the derivative equal to zero then do an increasing decreasing test to see whether or not you got a max or a min, usually it will be a max anyways but its always good to show your work

anonymous · Answer

the roots of the function will be the max or the min

anonymous · Answer

the derivative that is

anonymous · Answer

also that x value you find is the level of production
