Your manufacturing costs are C(x)= .0001x2+25x+1200 and the demand for X units of a certain commodity is p(x) =55 – x/1000. What is your maximum revenue and maximum profit?

you know about max/min and derivatives, right? what's the problem?
revenue is demand times price
profit is revenue minus cost
you have the formulas. use 'em.
