Two groups of campers carry their water in reusable packs that come in three sizes. The table shows how many packs each
group carries. A medium water pack holds 1 liter more than a
small pack holds. A large pack holds 2 liters more than a small
pack. Do the two groups carry the same amount of water? If not,
which group carries more? Use w to represent the number of
liters of water a small pack can hold. Show your work.
