Elam is packing his room to move into a new house. a small box can hold 8 books without breaking, while a large box can hold 12 books without breaking. he has at most 160 books to pack and less than 30 boxes total. let s represent the number of small boxes and l represent the number of large boxes. the inequalities s ≥ 0 and l ≥ 0 are part of the system that models this scenario. which inequalities complete the system? s – l < 30 8s – 12l ≤ 160 s + l < 30 8s + 12l ≤ 160 s + l > 30 8s + 12l ≤ 160 s + l < 30 8s + 12l ≥ 160
