Question 1100674: A certain manufacturer found that the marginal cost C to produce x DVD/Blu-ray players can be found using the equation C = 0.04x^2-6x+800. If the marginal cost were $599, how many DVD/Blu-ray players were produced?

You can put this solution on YOUR website!
599=0.04x^2-6x+800
14975=x^2-150x+20000
x²-150x+5025=0
Using the quadratic formula, we get two values of 99.5 and 50.5. So, it is most likely that 100 DVD/Blu-ray players were produced
