20.40=X(1-.15)
20.40=.85X
X=20.40/.85
X=$24.00 FOR THE PRICE BEFORE THE DISCOUNT.
PROOF:
24.00-(.15*24.00)=20.40
24.00-3.60=20.40
20.40=20.40

Let x = the original price of the item, then:
x-0.15x+=+20.40 The original price (x) minus 15% discount (0.15) of x = $20.40
0.85x+=+20.40 Divide both sides by 0.85
x+=+24
The original price was $24.00
