Problema Solution
Aki's Bicycle Design has determined that when x hundred bicyles are built, the average cost per bicycle is given by C(x)=0.2x^2-1.6x+5.718, where C(x) is in hundreds of dollars. How many bicycles should the shop build to minimize the average cost per bicycle?
Answer provided by our tutors
by differentiating
c"(x)= 0.4x - 1.6<0
0.4x < 1.6
x = 4..
atleast 4 bicycles..
