so, if we take 68.73 to be the 100%, what is 12 in percentage off of it?

[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 68.73&100\\ 12&p \end{array}\implies \cfrac{68.73}{12}=\cfrac{100}{p}\implies p=\cfrac{12\cdot 100}{68.73}[/tex]

seems Audryn is being generous, she probably got the silverware and the maple leaves tablecloth.
