Question

The cost for a company to manufacture x bracelets can be represented by the function C(x). Complete the sentence below using the answer choices:

If C(256)=1536, then the cost to the company is------$ to manufacture----------------- bracelets .
answer1----------option 256 or 1536
Answer2---------option 256 or 1536

Answer 1

$1536 divided by $256 is $6 per bracelet.

Answer 2

The cost for a company to manufacture "x"....
These statements tell you what X is. (The word cost refers to what the function will tell us. In other words C(x) = The Cost for the Company))

So as we keep going the problem goes onto:
.... bracelets
So the number of bracelets is X.

The function is: C(x)

And how functions work are quite simple. You plug in a number (x) and get out a number (y).

So, C(256) = 1536

So, they made 256 bracelets at a cost of 1536 dollars.

This is no different than if I said the function was:
C(x) = 6x
And then asked, what would the function equal when x = 256. It's the same thing, so don't let it trip you up!

Answer 1: 1536$
Answer 2: 256
