wolverine [178]

Solution:

<u>We know that:</u>

Original \ price = \$11

\frac{9.25}{11} + \frac{1.75}{11} =100\%

<u>Simplify the equation to find the percent off:</u>

\frac{9.25}{11} + \frac{1.75}{11} =100\%

84\% + \bold{16\%} = 100\% \space\ \space\ \space\ \ \ \ \ [Rounded]

This means that the <u>original price</u> has decreased about 16%.
