If the net price of a stove is $900 and the trade discount rate is 40%, then the list price is

$1,500

P/R $900 net price (P) trade discount rate is 40 percent. Must use complement (100 percent – 40 percent) since the portion (net price) represents 60 percent of the list price. $900/.60 = $1,500 (B)

Hope I helped
