#$21.25# with a #4.25%# sales tax would be #30.28#.

Explanation:

#4.25% = 0.425#
#100% =1#
Adding sales tax to the price of something is equal to paying for 100% of the item plus to tax percentage:
#21.25*1+21.25*0.425#
#=21.25*(1+0.425)#
#=21.25*1.425*#
#=30.28125#
In dollars, that would be #$30.28# because dollars only go up to two decimal places.
