Aki's Bicycle Designs has determined that when x hundred bicycles are built, the average cost per bicycle is given by C(x)=0.2x^2-0.1.8x +9.871 where C(x) is in hundreds of dollars. How many bicycles should the shop build to minimize the average cost per bicycle?
The shop should build ______ bicycles.
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! C(x)=0.2x^2-1.8x +9.871 where C(x) is in hundreds of dollars.
How many bicycles should the shop build to minimize the average cost per bicycle?
---
Minimum "C" occurs when x = -b/(2a) = 1.8/(2*0.2) = 4.5
---
The shop should build (rounding up to 5) bicycles.
