Find the maximum prot and the number of units that must be produced and sold in order to 1,rield the maximum prot. Assume that revenue, Flint]. and cost, IBEX}. are in thousands of dollars. and x is in thousands of units. R{X]=EKExz. C{x}=x3 5x2 +4x+1 The production level for the maximum prot is about |:| units. {Do not round until the nal answer. Then round to the Iwhole number as needed.) The prot is about $|:|. [Do not round until the nal answer. Then round to the I.IIrlmle number as needed.)
