Question 1177138
<font face="Times New Roman" size="+2">


Average cost is the cost function divided by *[tex \Large x]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  CA(x)\ =\ 0.1x\ -\ 0.7\ +\ \frac{2.245}{x}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{dCA}{dx}\  =\ 0.1 -\ \frac{2.245}{x^2}]


Set the first derivative equal to zero and solve for *[tex \Large x] and round to 2 decimal places. Since *[tex \Large x] in the cost function represents a number of 100 bicycles, any greater precision in the computation of the quantity for the minimum average cost would result in a minimum quantity including a fractional part of a bicycle.


Once you have the minimum quantity, evaluate the cost function for that quantity.
