so we know there are 3lbs of peppermint sticks in the candy, and we know 75% of the candy is white chocolate... if 75% is chocolate, that means 25% is peppermint sticks....so how much is 75% then? let's say is "x"
so part A) [tex]\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
3&25\\
x&75
\end{array}\implies \cfrac{3}{x}=\cfrac{25}{75}[/tex]
part B) solve for "x"
