Question

the total cost function is given by c=x^2+5x+200 where x is the number of units manufactured find average cost function when x=10...

​

Answer 1

Answer:

35

Step-by-step explanation:

It can be done in two ways.

Firstly we can find the total cost of x=10 by putting x=10 in the cost function and then divide the total cost by 10.

putting x=10 we get, C= (10)^2+5*(10)+200= 350

Now, average cost = 350/10 = 35.

Secondly, we can find the average cost function by dividing the cost function with x.

so, average cost function comes out to be

A(x) = x+5+(200/x)

Now putting x=10 in this average cost function we get

Avg = 10+5+(200/10) = 35.
