Final answer:
Camden's shot improved by approximately 10.71%.
Step-by-step explanation:
To calculate the percentage improvement in Camden's shot, we need to find the difference between his initial and final shot distances, and then divide that difference by his initial distance.
The difference in distances is 7.75 - 7 = 0.75 feet.
Now, we divide the difference by the initial distance: (0.75 / 7) * 100 = 10.71%.
Therefore, Camden's shot improved by approximately 10.71%.
