Question

David pays a 20% income tax on his $2,100 salary. How many dollars is the tax?

Answer 1

The guy on top of me is right so 20% of 2100 is 420
So the tax is $420
Then 2100-420= 1680
So he has $1680 left after paying the tax. u can just do 20% x 2100 then 2100-420= 1680 which is basically what he said

Answer 2

20% of 2100 is 420
So the tax is $420
Then 2100-420= 1680
So he has $1680 left after paying the tax.
