Question 748977
If the discount is 20% to begin with, then the customer would only pay 80% of the original price:

{{{310*(0.80)}}}

{{{248}}}

So the first sale price was $248.  Then the price was discounted another 25%, which means the customer would only pay 75% of the first sale price:

{{{248*(0.75)}}}

{{{186}}}

Thus, the clearance price is $186
