Easy,
finding the complement (net price) subtract the discount percentage by 100% to get the net price percentage. Net price equals the list price minus the discount price.
100%-35%=65%
Multiply the list price ($1,400) by the complement.
Net price= 0.65(1,400)=$910
Thus, the new price is, $910.
The answer would be a decimal so the answer is 7.4161984871.
