To find the difference between Jasmine's highest and lowest points, you can simply subtract the depth of the pool from the height of the diving board.
Height of the diving board = 10.5 feet
Depth of the pool = 8.2 feet
Now, subtract the depth of the pool from the height of the diving board:
10.5 feet - 8.2 feet = 2.3 feet
So, the difference between Jasmine's highest and lowest points is 2.3 feet.
