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

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
