Question

Determine an expression for the cost

Answer 1

Pi = MC squared + the radius of pathagorean theorum divided by the square root of exponent X

Answer 2

lol

Answer 3

i don't either.

Answer 4

its correct assuming you buy more than 100 chips, otherwise, no

Answer 5

you can define the cost function with the restricted domains

Answer 6

yes, use a piece-wise function

Answer 7

a piece-wise function

Answer 8

also you should usee p instead of n, as the question asked for that

Answer 9

yes

Answer 10

you'll need to give C no matter what amount is purchased though...

Answer 11

p>=100

Answer 12

\[[100, \infty)\]

Answer 13

for 0<=p<100
C(P)=200

Answer 14

C(P)=2p rather lol

Answer 15

its a piece-wise function and is linear

Answer 16

yw

Answer 17

I'm wondering if they also want it for under 100. Then you'd have two piecewise functions.

c(n)=2n,
n≤100


c(n) = 200+1.75(n-100) when n>100

Answer 18

But the first part... would they want that as well?

Answer 19

Oh I see.

Answer 20

Sorry, I didn't read through all the comments...

Answer 21

It's just a line. First, get it in slope-intercept form.

c(n) = 200+1.75(n-100)
= 200 +1.75n - 175

c(n)=1.75n +25

Your y-intercept is 25. Your slope is 1.75.

Answer 22

Looks good.

Answer 23

just in case, because the problem did not state that they'll aways buy more than 100 chips, the function should look like this:
