JQuery - set a variable equal to another

I know...this should be stupid simple but I am new to JQuery/JavaScript and this particular situation has me stumped. Most of what I do is plagiarized from studying snippets and just trying things over and over until I get the syntax right.

I have this line defined in a function:

$("#regularfee").text("25.00");

which of course allows me to have it displayed in my div "regularfee" in my html. This is working no problem.

All I want to do is at a later point within the same function set a different variable equal to the first.

I fully understand just saying: var newvar = oldvar and such...but when it is represented as above I can't seem to find the right syntax to make it happen. I promise...I have searched for a couple of hours but have not been able to find an example that works for me...please be gentle! LOL!

Additional info:

Here is a bit more detail... 

$("#regularfee1").text("30.00"); // this displays just fine in my <div>
$("#regularfee").text("25.00"); // this displays just fine in my <div>
var regularfee = 25;  // now *really* set the var...this is what I did not realize
var regularfee1 = 30;

// some other non-relevant code...
// I have another <div> in my html <div id=regselectedfee>
// and I have a conditional that sets regselectedfee based on the conditional

// now I want to have the <div id=regselectedfee> display its newly set value.
// How do I set $("#regularselectedfee"). ??? to show either regularfee or regularfee1 variables?

What is the syntax of this line to make that happen?

I hope I'm stating this a bit more clearly...

Hi you can do it like this

var somevalue = 25.00;

$("#regularfee").text(somevalue);

then you can change the variable value after like this

somevalue = 30.00;

or you can do

var another = somevalue;

This is the syntax: mynewvar=$("#regularfee").text(); (assuming $("#regularfee") has no children elements; if it does, try $("#regularfee:first").text(); see the jQuery .text() method documentation for detail).

Though it may be faster to do something like this:

var regular_fee="25.00",
    mynewvar;

$("#regularfee").text(regular_fee);
mynewvar=regular_fee;

Do you mean something like this?

var oldvar = "25.00";

$("#regularfee").text(oldvar);

var newvar = oldvar;
