Oliver is working two summer jobs, making $7 per hour washing cars and making $10 per hour clearing tables. In a given week, he can work no more than 12 total hours and must earn no less than $90. Also, he must work no less than 4 hours washing cars. If xx represents the number of hours washing cars and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.

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

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
