Lizzy: Jackson collects 45 hermit crabs, 3 spiral shells per hermit crab, and 2 starfish per spiral shell. How many souvenirs does he collect total?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find the number of spiral shells Jackson collects: 45 hermit crabs * 3 spiral shells / hermit crab = 135 spiral shells. Then find the number of starfish he collects: 135 spiral shells * 2 starfish / spiral shell = 270 starfish. Then add the number of each animal he collects to find the total number: 135 spiral shells + 270 starfish + 45 hermit crabs = 450 souvenirs. Final answer: 450.
