Sales tax in the state of Florida is 7% Tiffany purchased a coat that was marked at $35 how much was her total bill including tax
The total bill including tax can be calculated by multiplying the cost of the coat by the sales tax rate and adding it to the cost of the coat.
So, the sales tax on the coat will be $35 * 7% = $<<35*7*.01=2.45>>2.45.
Therefore, Tiffany's total bill, including tax, will be $35 + $2.45 = $<<35+2.45=37.45>>37.45. Answer: \boxed{37.45}.
