Point Success: $14,164$ feet Rainier: $14,416$ feet Matlalcueyetl: $14,636$ feet Steele: $16,624$ feet McKinley: $20,237$ feet

Work Step by Step

To sort the mountains from shortest to tallest, we first take the absolute value of the "altitude" column, and then arrange the numbers from smallest to largest: Point Success: $|14,164|=14,164$ feet Rainier: $|14,416|=14,416$ feet Matlalcueyetl: $|14,636|=14,636$ feet Steele: $|16,624|=16,624$ feet McKinley: $|20,237|=20,237$ feet (Here the absolute value does not change the values, as all the numbers are already positive.)
