Todd uses the quadratic regression model to determine the predictive average unit cost of
baseballs produced in his production facility. After determining predictive average costs at
multiple unit batch size amounts in millions, he now wants to know what the output level that
maximizes his costs would be. Given b1 = 0.3802 and b2 = 0.0198, what is the level that will
maximize his average cost in units? Multiple Choice 19.20 million units 7.5 million units
