Tickets at a movie theater cost $9 for adults and $6.75 for children. Tickets sales for one movie showing totaled $1406.25. The equation 9a+6.75c=1406.25 models the situation, where a, represents the number of adult tickets sold and c represents the number of child tickets sold

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
