Lets say we have a product that costs 100$ (net price). This product has 3 taxes that must be applied to it: 2 percentage taxes (e.g. 17% and 20%) and one fixed amount tax (e.g. +10$).
My question is - what math is done in this case?
Are the percentage taxes applied on the net price and summed or the first one is calculated and then the second one is done with the price we get after applying the first? When is the fixed amount tax applied? After the other two or the other two are done with net+fixed tax?
