Answer: 67.90 dollars
========================================
Work Shown:
30% = 30/100 = 0.30
Take 30% of 97 to get 0.30*97 = 29.10
So Ingrit saves $29.10
The sale price is 97.00 - 29.10 = 67.90
-----------
Here's another way to get the answer:
The discount is 30% which means she saves 30% and pays the remaining 70% (since 30% + 70% = 100%)
70% = 70/100 = 0.70
Take 70% of the original price and you'll get the sale price
0.70*97 = 67.90
