6. A pizza's original price is $11. It is on sale for $9.25. What percent off is it?

wolverine [178]

Solution:

We know that:

$Original \ price = \$11$

$Sale \ price = \$9.25$

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

Simplify the equation to find the percent off:

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

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

This means that the original price has decreased about 16%.
