 Question 23274: Maximum cost using the quadratic equations, functions, inequalities and their graphs. It costs Acme Manufacturing C dollars per hour to operate its golf ball division. An analyst has determined that C is related to the number of golf balls produced per hour, x, by the equation C = 0.009x^2 - 1.8x + 100. What number of balls per hour should Acme produce to minimize the cost per hour of manufacturing these golf balls? Click here to see answer by Earlsdon(6287)

 Question 23275: Maximum profit using the quadratic equations, functions, inequalities and their graphs. A chain store manager has been told by the main office that daily profit, P, is related to the number of clerks working that day, x, according to the equations P = -25x^2 + 300x.
