I can buy office supplies @ walmart with a 30/10 chain discount. If I paid $47.25 for adding machine. What was the regular price of my purchase?

Please explain the term "30/10 chain discount". Which of those numbers is the discount? Does the 30 mean "if paid within 30 days?"
If the discount from the regular price is 10% and you paid $47.25, the regular price is
(1/0.9)x($47.25) = $52.50
