Php百分比

Question

I'm trying to add a mark up percentage to the $cents per Mile, for some reason it ignores it. How can I create a var that I can enter a whole number for percentage and have it add it to the cost?

<?php 
$PriceofgallonGas = 2.59 ;
$precent = 50 ; 
?>



<?php
    function installVanFuel() {

        global $PriceofgallonGas,$precent;
        $TankMiles = 254;   
        $SizeofTankinGallons = 31;
        $mpg = $TankMiles / $SizeofTankinGallons;

        $markup = (1 + $percent/100);
        $centsPerMile = $PriceofgallonGas/$mpg;  
        echo round($centsPerMile*$markup, 2); 
    }
?>

You have a spelling mistake, please check.

At $markup = (1 + $percent/100); you miss spelled the variable $percent.

$PriceofgallonGas = 2.59 ;
$precent = 50 ; 

function installVanFuel() { 
    global $PriceofgallonGas, $precent;
    $TankMiles = 254;   
    $SizeofTankinGallons = 31;
    $mpg = $TankMiles / $SizeofTankinGallons;

    $markup = (1 + $precent/100);
    $centsPerMile = $PriceofgallonGas/$mpg;  
    echo round($centsPerMile*$markup, 2)." Cents x ".$precent."%"; //0.47 Cents x 50%
}
installVanFuel();
