>>>I then have to add another 7,5% to that intermediate result which gives me the grand total.

>>>So if the product is $150 the intermediate result would be $160,50
>>>I then take the $160,50 to add the remaining 7,5% which gives a grand total of $172,54

>>>Now here's the problem I want from a given total price be able to go back to the point where I have the original amout without the taxes.
