so 10.5 millions would be the 100% then, now, minus 6%, we'd end up with 100-6 is just 94% then, now, how much is 94% of 10.5?
well [tex]\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
10.5&100\\
x&94
\end{array}\implies \cfrac{10.5}{x}=\cfrac{100}{94}[/tex]
solve for "x"
