Question

Omar wants to fill his backpack for a school field trip. His backpack is 30 litres. Omar

packs his essentials which took up 15 litres. He wants to bring along some video games
which take up 1 litre each and he does not necessarily want to fill up his backpack. What
are the possible number of video games that Omar can put in his backpack?

Answer 1

Since the full capacity is 30 litres, all we need to do is 30 - 15 which equals 15 litres.

If he does not wish to fill up his bag instead of 15 videogames (the max amount.), he can put 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1.

Hope that helps. x
