The Lighthouse Keepers Supplies - RI.5.1-4 & 5.NBT.5/6

One morning, a supply boat arrived with 2,340 pounds of oil to fuel the lamps. The barrels were heavy, and each weighed 45 pounds. George needed to determine how many barrels were on board so he could organize storage in the lighthouse basement.
