Do you know what \(25\%\) is?
OpenStudy (skullpatrol):
Do you know what percent means?
OpenStudy (anonymous):
Be right back... 10 mins.
OpenStudy (anonymous):
and yes i do
OpenStudy (anonymous):
100%:25% so 4:1. Now you can simply multiply 4 by $275 and that will be your answer

How to do it. And you're right, it did not help...
Parth (parthkohli):
Okay, Skullpatrol and I will help you. :-)
OpenStudy (anonymous):
I just do not get it,and Id appreciate explanations
OpenStudy (anonymous):
thanks,parth and skull.
Parth (parthkohli):
The first question is: What do you mean by "percent"?

OpenStudy (anonymous):
outof a hundred.
Parth (parthkohli):
And so what is, "25%"?
OpenStudy (anonymous):
25 out of a hundred
Parth (parthkohli):
So if her income is represented by "hundred", then the amount she paid is twenty-five. Do you get what I mean?
OpenStudy (anonymous):
yes...

Parth (parthkohli):
The answer is not $25!
Parth (parthkohli):
OK, let me get back to the question. What do we want to find according to the question?
OpenStudy (anonymous):

Parth (parthkohli):
Exactly, so we can always call the thing our questions wants \(x\), correct?
OpenStudy (anonymous):

Parth (parthkohli):
That's the word! Yes, so now let's see what the question means.
The question says that \($275\) is \(25\%\) of \(x\). Right?
OpenStudy (anonymous):
oh,righttt!
OpenStudy (anonymous):
let me try to set it up as a proportion,
Parth (parthkohli):
You can do that, but you could also set up an equation. That'd make more sense.
OpenStudy (anonymous):
275/x=25/100?

Parth (parthkohli):
But there are two ways to solve the same problem, so go ahead. :-)
Parth (parthkohli):
Yes, that's correct!
OpenStudy (anonymous):
yay! thanks for helping!
OpenStudy (anonymous):
now ill solve...
Parth (parthkohli):
Just to confirm, what'd you get for \(x\)?
