Answer:

p = $340

Step-by-step explanation:

Let p represent the original price.  Then the amount Mary paid was (100% - 74%) of the original price:  0.26p = $88.40.

Solving for p:  p = $340

Check:  what is 74% of $340?  $251.60.  Subtracting this from $340, we get $88.40.  This agrees with the problem statement.
