To find the percent change from the old price to the new price, you can use the formula:
\[
\text{Percent Change} = \frac{\text{New Price} - \text{Old Price}}{\text{Old Price}} \times 100\%
\]
In this case, the old price is $6 and the new price is $5. Plugging in these values, we have:
\[
\text{Percent Change} = \frac{5 - 6}{6} \times 100\%
\]
\[
= \frac{-1}{6} \times 100\%
\]
\[
= -\frac{100}{6} \%
\]
\[
= -16.67\%
\]
The negative sign indicates a decrease in price. Therefore, the percent change is approximately **-16.67%**.
