The cost of the jeans will be reduced by $7 which will be $14. Divide 21 by 3 to get 7 and subtract that from 21 leaving 14. 3% of $14 would be .03 * 14 = 0.42. So the tax paid would be $0.42.

if the price of a $21.00 pair of jeans is reduced by+1%2F3 we will have a new price which is:
21.00-+%2821.00%2F3%29+=+21.00-+7.00+=+14.00+$
and if state sale tax is 3%
Tax_to_+be+_paid+=+x$ will be:
x+=+14.00%283%2F100%29
x+=+14.00%28.03%29
x+=+0.42$
