\text{What You Think Upon Grows Day}

===

Today (May 31) is What You Think Upon Grows Day! What does that entail? Who knows!

Unknown to you, it is What You Think Upon Grows Day. You're in class thinking about your Labrador puppy, Dr. Pupper, who's a foot tall. This class is pretty simple so you spend about $50\%$ of your time thinking about Dr. Pupper. After five hours, the class ends and you head home. Not only did Dr. Pupper grow, but she experienced continuous exponential growth! How tall is Dr. Pupper now?

Round your answer to the nearest foot.
