A manufacturer of tennis balls has a daily cost of C(x) = 0. 01x2 – 10x + 4000, where x is the number of tennis balls produced. How many tennis balls should be produced to minimize the cost? What is the minimum cost?
Answer: x=500+100sqrt{15}i OR x=500-100sqrt{15}i Step-by-step explanation: 0.01x^2-10x+4000=0 solve for x using quadratic formula Answers are imaginary numbers, possibly due to wrong equation in question
