I am trying to find out the discount amount of a price.
The cost of item WAS £50.00 Sale Price £25.00 Discount = %50
However when use this formula below in PHP it doesnt give me the correct Discount percentage.
$percent = $rowx->Orgprice - $rowx->SalePrice / 100;
$percent = 50 - 25 / 100 = 49.75;
$percent = 50 - 20 / 100 = 49.8;
All above percentages are wrong.
