Answer: $59.25</h3>
========================================================
Explanation:
There are two approaches
Method 1
25% of 79 = 0.25*79 = 19.75
Mary saves $19.75 and the price before tax is 79 - 19.75 = 59.25
-----------------------------
Method 2
She saves 25% so she must pay the remaining 75%
75% of 79 = 0.75*79 = 59.25
