Regular price:  $419
Sale price:  (1-0.205)($419) = $333.11
The bike will cost $333.11 before tax.  You haven't shared the tax rate, but I can at least tell you that the cost of the bike after tax will be 
(1.00 + rate as a decimal fraction)*$333.11.
Example:  If the tax rate is 7.5%, then the bike will cost (1.00+0.075)*($333.11).
