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.
 
160+.006x
 
 
 
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(x)=
 
 
 
 
C(10,000)
= $

Expert Answer

Step 1

C'(x)= 160+.006x

C'(10000)=160+.006(10000)=220

Answer: The cost is increasing by $220 per smart phone when x = 10,000.

Step 2

To find exact cost of 10,001 smartphone, we plug x=10001 in C(x).

The cost is increasing at a rate of $ 220  per smartphone. The exact cost of producing the 10,001st smartphone is $ 2300220  . Thus, there is a difference of $ 220  .

C(x) 400,000+160x+0.003x2
C(10001) 400,000+160(10001)+0.003(10001)
C(10001)-2300220
