Answer:
Explanation:
the easiest thing would be to take $21.70 divide that by 4 then you will get $5.425 and then if you times that by 4 you get $21.70 it also depends on the state for tax but I would say that $23 on the safe side so I would say that the answer is 1% tax rate hope this helps and good luck.
P.S this may be wrong but i hought it would try to help :)
