Problem of the Day

Chapter 13, Lesson 10

While driving, Theresa reaches a point on a road where two signs are posted. The first sign says that for the next 5 miles, the road slopes down at a 4% grade (this means that for every 100 feet traveled, the road goes down 4 feet). The second sign says that the road is now at 9600 feet above sea level.

How many feet above sea level will Theresa be at the end of the 5 miles? Explain your reasoning.
