%change=100(final-initial)/initial

%change=100(25.95-32.88)/32.88

%change≈ -21.08%

So the percent decrease in price was about 21%
32.88 - 25.95 is 6.93

well, if we take the 32.88 to  be the 100%, how much is 6.93 off of it in percentage?

[tex]\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 32.88&100\\ 6.93&x \end{array}\implies \cfrac{32.88}{6.93}=\cfrac{100}{x}[/tex]

solve for "x".
