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.
