Question 184112: Aki's Bycycle Designs has determined that when x hundred bicycles are built, the average cost per bycycle is given cy C(x)=0.7x^2-1.3x+10.679, where C(x) is in hundreds of dollars. How many bicycles should the shop build to minimize the average cost per bicycle?
I don't know where to begin with this problem, can someone please help me with it? I would really appreciate it.

You can put this solution on YOUR website!
If you know calculus, take the derivative, set that to 0 and solve for x.
If you don't know that yet, find the minimum of the parabola. Here is a URl with the formula on it --> http://www.tpub.com/math1/17e.htm
