Work Step by Step

The relationship is between the number of flights of stairs climbed and elevation (ft above sea level). So if 0 flights of stairs climbed, you start with 311 ft above sea level. If 1 flight of stairs are climbed, you are at 326 ft above seal level. If 2 flights of stairs are climbed then you are at 341 ft above sea level. If 3 flights of stairs are climbed then you are at 356 ft above sea level. We can see that the difference between the ft above sea level is constantly 15 ft. So therefore, we can conclude that each flight of stairs climbed brings you 15 ft above.
