Aya sells stuffed animals at a craft fair. She charges $\$13$ for the small ones and $\$12$ for the large ones. She sold $\$350$ worth of animals. After the show, she noticed that she sold 27 stuffed animals. How many were small and how many were large?
+36916 s = small value = 13s
l = large = 27-s value = 12(27-s) summed = 350
13s + 12 (27-s) =350 solve for 's' then l = 27-s
