If you were babysitting, would you rather Charge $5 for the first hour and $8 for each additional hour?
Or

Charge $15 for the first hour and $6 for each additional hour?
Explain your reasoning.

Depends on how long. $8 every additional hour would be the better deal unless you go at or over 6 hours. If you're planning on babysitting for 5 hours or less, go with option A. If 6 hours or more, go with option B.

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
