Answer:
She is paying 88% or .88 of the original price.
Explanation:
Sales tax is 8%, which adds .08 to the price she is paying.
The discount is 20%, which subtracts .20 from the price she is paying.
(1.00+.08) - .20 = 1.08 - .20 = .88
.88 is the same as 88%, so she pays a total of 88% (with sales tax included).
