Hi so if you start at 1.60 and go up by 60% you first look at what 10% of 1.60 is wich is 0.16 then do 0.16 * 6 = 0.96 then do 1.60 + 0.96 = 2.56 then go down by 20% so 10 % is 0.16 and then 20% is 0.32 so then do 2.56 - 0.32 = 2.24 i really have to go now so if you can do the tax part yourself then that would be great!
