Question

For the given cost function C(x)= 14400+800x+x^2 find: a) The cost at the production level 1750 b) The average cost at the production level 1750 c) The marginal cost at the production level 1750 d) The production level that will minimize the average cost e) The minimal average cost

Answer 1

I have everything except for d and e which seems to be the most difficult. I keep searching online but have not seem to find the answer to my problem.

Answer 2

I always skipped the explanations for these things but..
if x = production level
C = cost at a given production level
I know what to do

Answer 3

Cool well can you help with d and e?

Answer 4

Back

Answer 5

Are my assumptions correct?

Answer 6

Wait did you try answering it? I am new to this. This is my first time here.

Answer 7

I just had a problem connecting the terms in the description of the problem with the equation. Not familiar with standard form

Answer 8

if x = production level
C = cost at a given production level
I know what to do

Answer 9

Oh well if this helps A) is 4476900, B) is 2558.23, C)4300

Answer 10

Is it true that x = production level and that C(x) = cost? !!!!

Answer 11

Yes it is true.

Answer 12

Then what we want is the minimum of the cost as a function of production.
That is obtained by taking dC/dx and setting it equal to 0. Are you OK with derivatives?

Answer 13

the derivative of the first function i have that answer which is 2x+800

Answer 14

x=-400 but when i plug it in and it says it is wrong

Answer 15

Yeah. Production can't be < 0. Sit on your retriceall day, it's still 0.

Answer 16

They removed my bad word somehow!

Answer 17

It's not 0 plugged it in and it's wrong

Answer 18

2 things:
problem /answers are wrong
I'm wrong
get some help OK?

Answer 19

Okay thanks for the help though
