n1concepts Posted March 2, 2013 Share Posted March 2, 2013 Hi, I need some help to define a math equation, in PHP, that will determine the variable $y. Example: (1.60 multiplied by 718) then divided by 3550 equals 0.328 (rounded up) Equation: (1.60 * 718) / 3500 = 0.328 ---- What i need to do is define a PHP formatted equation that will pass in the following: $p = 1.60; $c = 3500; $e = 0.328 Which will then determine $y (which in the above example is 718)? Note: should either of the other three variables change ($p, $c, $e), then $y value will dynamically adjust accordingly. ------ Any insight on how this can be defined in PHP appreciation - thx! Note: I know the format - already stated - will work in PHP; I need to figure out how to render $y based on other known variables ($p, $c, $e) That's my issue and my calucations - even knowing 718 is the answer based on those plugged in values - is unknown. thx!

rgopal101 Posted March 2, 2013 Share Posted March 2, 2013 Try This $y=($p * $c) / $e ; Link to comment https://forums.phpfreaks.com/topic/275123-need-to-figure-out-variable-y-structure-to-define-in-php/#findComment-1416002 Share on other sites More sharing options...
n1concepts Posted March 2, 2013 Author Share Posted March 2, 2013 Thanks but that doesn't yield 718; intead 17073. I know this should be simple to define but guess I've been out of school too dog-gone long... LOL!!!! I'll continue to play w/it until i figure it out but thanks!

n1concepts Posted March 2, 2013 Author Share Posted March 2, 2013 I figured it out - simple math (had to step thru to get to 2nd step). Always, look for the simple method/answer...
