Today, the mountain that contains Mount Rushmore is approximately 5,675 feet high. The height of the mountain is 622.5 feet less than 1.1 times its height before construction began.

The equation to find the height of the mountain prior to construction, represented by the variable h, is

1.1h – 622.5 = 5,675

Solve an equation to find the height of the mountain prior to construction, represented by the variable h.
