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. x machines are made, then the unit cost is given by the function C(x)=0.9x^2-414x+65,441. What is the minimum unit cost do not round your answer.

Isee the amount was $90.00 then reduced to $75.00 , what is the percent ?
