Maria purchased a book at a discount. The discounted price of the book is modeled by the equation a=b-xb. What do a, b, and x most likely represent in this equation? a = amount Maria paid; b = original cost of the book; x = discount percentage
a = original cost of the book; b = amount Maria paid; x = discount percentage
a = amount Maria paid; b = original cost of the book; x = total discount on the book
a = original cost of the book; b = amount Maria paid; x = total discount on the book
