Question
Assume that it costs a company approximately
C(x) = 400,000 + 140x + 0.001x²
dollars to manufacture x smartphones in an hour.
(a) Find the marginal cost function.
Use it to estimate how fast the cost is increasing when x = 10,000.
$
per smartphone
Compare this with the exact cost of producing the 10,001st smartphone.
The cost is increasing at a rate of $
per smartphone. The exact cost of producing the 10,001st smartphone is $
Thus, there is a difference of $
(b) Find the average cost function C and the average cost to produce the first 10,000 smartphones.

C(10,000) = $
(c) Using your answers to parts (a) and (b), determine whether the average cost is rising or falling at a production level of 10,000 smartphones.
The marginal cost from (a) is higher
* than the average cost from (b). This means that the average cost v ---Select---
at a production level of 10,000 smartphones.
