A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of machines made.

If x machines are made, then the unit cost is given by the function C(x)=0.2x^2-40x+6768. How many machines must be made to minimize the unit cost?
