A squirrel climbs 15 feet up a tree. He then runs 8.26 feet down the tree. How much further does the squirrel need to go before reaching the ground?

The squirrel starts 15 feet above the ground and runs 8.26 feet down, so subtract: 15 − 8.26 = 6.74 feet. He needs to go 6.74 feet farther to reach the ground, which is choice C.
