Sales tax: $$ 4.08$ $$4.08$
(Total after tax price: $$ 72.08$ $$72.08$ )

-To start off, we need to find the "sales tax." To do that we need to divide $2.10 by $35:

$\frac{2.10}{35} = 0.06$ $2.10/35=0.06$ *

* $0.06$ $0.06$ = sales tax

-Now, multiply the sales tax by the next item, in which costs $68.

$0.06 \cdot 68 = 4.08$ $0.06*68=4.08$ *

*4.08= the amount of tax added to the original price:

$4.08 + 68 = 72.08$ $4.08+68=72.08$ <-----dollars
