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 $ to bracelets .
256 or 1536
256 or 1536

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

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
