Answer:
The original cost of the DVD was $21`.59
Step-by-step explanation:
In order to find this, you first must note that the new price is 88% of the older price. We get this since there was a subtraction of 12%. 
Now knowing that, we can divide the new price by the percentage paid and it will give us the original price. 
$19/88% = Original Cost
19/.88 = Original Cost
$21.59 = Original Cost
