[AI-generated answer — Bot GPT 3.5]

To predict the average final grade percentage if a student spent 10 hours on social media, we can use the given equation:

y = -7.2x + 98.9

Substitute x = 10 into the equation:

y = -7.2(10) + 98.9
y = -72 + 98.9
y = 26.9

Therefore, if a student spent 10 hours on social media, the predicted average final grade percentage is 27%.
