Ed and Jacob already had 2 shells in their shell collection. Then they went to the beach to collect even more. Ed found 7 limpet shells, 2 oyster shells, and 4 conch shells. Jacob found 2 more shells than Ed did. How many shells do the pair have altogether?
Ed found 7 shells + 2 shells + 4 shells = <<7+2+4=13>>13 shells at the beach.
Jacob found 13 shells + 2 shells = <<13+2=15>>15 shells at the beach.
In total Ed and Jacob have 2 shells + 13 shells + 15 shells = <<2+13+15=30>>30 shells.
