Assume that it costs a company approximately C(x) = 400,000 + 160x + 0.003x² 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 $ (b) Find the average cost function C and the average cost to produce the first 10,000 smartphones. C(x) = 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 ---Select--than the average cost from (b). This means that the average cost is ---Select-- Thus, there is a difference of $ at a production level of 10,000 smartphones.

Question
Assume that it costs a company approximately
C(x) = 400,000 + 160x + 0.003x²
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 $
(b) Find the average cost function C and the average cost to produce the first 10,000 smartphones.
C(x)
(10,000)

per smartphone. The exact cost of producing the 10,001st smartphone is $
$
(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 ---Select--- than the average cost from (b). This means that the average cost is ---Select---
Thus, there is a difference of $
at a production level of 10,000 smartphones.
