Percent of decrease is 63%

#### Explanation:

Original price is $15 at 100% Sale price is $5.50 at $x$

Then: ($15)/($5.50) = (100%)/x

Cross multiply: 15x = 5.50*100%

x = (550%)/15 = 36.67% Which is the sale price percent.

To find the percent of decrease we need to subtract the sale price percent from the original 100%

100% - 36.67.% = 63.3% rounded off to 63%#
