The cost of flying x kilometres is C(x) = 0.0225x + 165.1. The average cost A(x) is found by dividing C(x) by x. Find and interpret lim x→∞ A(x).
I know the answer is 0.0225, but I don't know how to interpret it.. u.u
Divide C(x) by x to get A(x) =0.0225 + (165.1)/x
Now,as x gets very large (tends to infinity) (165.1)/x gets very small (tends to zero) leaving
only 0.0225 which is your answer.
