Answer:</h3>
12%
<h3>
Step-by-step explanation:</h3>
Her discounted price was 100% - 20% = 80% of the original price. The service fee made it be 100% + 10% = 110% of that, so her final price was ...
... 110% × 80% = 88%
of the original ticket price.
This represents a discount of 100% - 88% = 12% from the original.
