Question

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.

Answer 1

The answer is s + l < 30
8s + 12l ≤ 160

Answer 2

Answer:

8s + 12l  <=160

s + l < 30

Step-by-step explanation:

Let s represent the number of small boxes and

l represent the number of large boxes.

A small box can hold 8 books without breaking, so its 8s

while a large box can hold 12 books without breaking, so its 12l

Total of 160 books

So 8s + 12l  <=160

small box + large box is less than 30

So s + l < 30
