How to assign a variable the value of a mathematical if statement?

[idontknowphp]

basically, I have one calculation that relies on the value returned by an if statement, but i can;t for the life of me figure it out correctly... Here is what i am trying to accomplish:

 

Here is the code for the IF i need to get the value of

if ($loadedMiles < 500) { 
	(500 - $loadedMiles) * .25 * $mainRate;
}

 

And here is the reason why i need it:

if ($loadSize == "Full") {
	$loadedmiles + thevalueoftheif;
}

 

basically i will need to have a way to get the values of the functions in the IF statements if that makes any sense...

 

thanks in advance!

Simply assign the result to a variable like so...

if ($loadedMiles < 500) { 
	$var = (500 - $loadedMiles) * .25 * $mainRate; // $var
}

if ($loadSize == "Full") {
	$loadedmiles + $var; // $var
}
