if we take the 850 to be the 100%, then how much is 6.5% of that?
[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 850&100\\ t&6.5 \end{array}\implies \cfrac{850}{t}=\cfrac{100}{6.5}\implies \cfrac{850\cdot 6.5}{100}=t[/tex]
so the tax is "t", add that to the 850 sale price, and the total price is 850 + t.
