0 ft.

[tex]\bold{SOLUTION:}[/tex]

To find the final height of the balloon, we need to calculate the net change in height.

The balloon rises 187 1/4 feet in 10 minutes, which can be expressed as +187 1/4 feet.

Then, it descends 187 1/4 feet over an hour, which can be expressed as -187 1/4 feet.

To find the net change, we need to subtract the descent from the ascent:

+187 1/4 feet - 187 1/4 feet = 0 feet

Therefore, the balloon's final height is 0 feet.
