Solve for x (get x by itself)
Add 5/y on both sides
Divide 4 on both sides to get "x" by itself
If dividing 4 confuses you, then you can do this:
Multiply 1/4 on both sides
Distribute 1/4 into (2z + 5/y)
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
As we know, sometimes questions such as these that include the powers and patterns can be a little confusing. I'll walk you through the process of finding this answer.
Firstly, we both know that 10 to the power of 2 simply means this :
10 * 10 = 100
Now, considering we already know what 10 to the power of 2 is, it makes the rest of the question a lot easier. All we have to do is divide 35.6 by the numbers we got.
35.6 / (10 * 10) = 0.356
There you have it, the answer is 0.356. If you need further assistance or you don't understand something, don't hesitate to ask me! I'm always open to people commenting on my profile or even sending me a private message. :)
