A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the number of machines made. If x machines are made, then the unit cost is given by the function C(x)=1.2x2 – 432x+50,313. What is the minimum unit cost? Do not round your answer. ​
