Question 889479: Classic Furniture Concepts has determined that when x hundred wooden chairs are built, the average cost per chair is given by C(x) = 0.1x2 − 0.7x +1.625, where C(x) is in hundreds of dollars.

A. –(b)/(2a)=-(-0.7)/(2)(.1)=3.5 350 chairs should be built to minimize the average cost per chair
B. (-b/2a,c(-b/2a))=(3.5,0.4)
$0.4 per chair is the minimum average cost
