A product can be produced at a total cost C\left(x\right)=700+100x^2+x^3C ( x ) = 700 + 100 x 2 + x 3 dollars, where x is the number produced. If the total revenue is given by R\left(x\right)=9,000x-80x^2R ( x ) = 9 , 000 x − 80 x 2 dollars, determine the level of production x that will maximize the profit.
