Tags:Problem Set 2 Geometry Algebra Prep

Harry is planting trees to attract wild birds to his garden. The idea is that the trees will provide habitat for nesting. He also plans to install a bird house and a couple of feeders for birdseed in each tree. How tall is a pink dogwood that is 25 feet shorter than a magnolia that is three times as tall as the dogwood?

Solution

If $x$ is the height of the dogwood, then $x + 25$ is the height of the magnolia, which is equal to $3x$ .

So $x = 12.5$ feet.
