Question 1157454: Aki's Bicycle Designs has determined that when x hundred bicycles are built, the average cost per bicycle is given by C(x)=0.5x^2-1.4x-1+2.134, where C(x) is in hundreds of dollars. How many bicycles should the shop build to minimize the average cost per bicycle? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! C(x)=0.5x^2-1.4x-1+2.134,
find the vertex
this is true when
b=-1.4, a=0.5
x = -b/(2a)
x = -(-1.4)/(2*0.5)
x = (1.4)/(1)
x = 1.4
.
solution: 1.4*100 =140 bicycles
