Regina got up early this morning to hike into the mountains and watch the sun rise. From the starting point, Regina climbed 47 meters in elevation. then she went steeply downhill, losing 36 meters in elevation. finally, Regina climed 10 more meters in elevation to the ledge where she watched the sub rise. which equation can we use to find out how may meters in elevation higher (m) Regina was at the ledge than she was at the starting point?
