Question

help finding average minimum cost

Answer 1

business calculus?
so when every you want to 'mimumize' or 'maxiumize' cost, take the derivative of the equation, and set it equal to zero, then solve for 'x' ^_^

Answer 2

@DemolisionWolf I got x=3/4

Answer 3

So then do I plug that into the equation?

Answer 4

x=3/4 is correct ^_^

Answer 5

okay then I plugged it into the equation and I got 586.3046317

Answer 6

and the problem says that the equation for average cost is C(x)/x

Answer 7

so 586.3046317/(3/4) ?

Answer 8

yes, plug that number into.. ya, then take 586.30 and put it as c(x) in the c(x)/x equation, and plug in 'x' also
haha ur too fast for me to respond ^_^

Answer 9

yes thats it ^_^
nice work

Answer 10

hahaha I'm sorry.

Answer 11

@DemolisionWolf Just a sec, though. that's not any of my answer choices :/

Answer 12

hmm..
what are the choices?

Answer 13

1. $348.33
2. $338.33
3. $328.33
4. $333.33
5. $343.33

Answer 14

oh, im sorry, i read the question wrong, we derived the wrong equation. we need to derive C(x)/x

Answer 15

oh I see.

Answer 16

...mmmm... let me work it out first hold on

Answer 17

yeah no problem

Answer 18

ok ya, thats the right way ^_^

Answer 19

@DemolisionWolf How do you derive it?

Answer 20

does it involve dx/dy ?

Answer 21

sorry, I was helping another person.
to derive this... .I dont like deriving this. I have a program that solves this stuff, so i gotta work it out by hand now :/ haha 1 minute

Answer 22

yeah no prob!

Answer 23

crap, i have to go at 4:00
I didn't finish this, but the derivative of the function becomes:
(100(3(log(x)-5)/(x^2)
