Farmer Frank has a busy day planned! He needs to harvest crops, sort eggs, and prepare for the Farmers' Market. He has given you the important job of feeding the animals. Uh oh—who shut the doors to the barn? Now they are locked and you can’t get to the food! How will you feed the animals?! Farmer Frank keeps his keys locked in a box for safekeeping, but he didn’t tell you any of the combinations. Can you figure out the combinations so you can get to the keys and open the barn doors? Hurry, it’s feeding time in 45 minutes!
