A researcher is analyzing the relationship between hours studied and exam scores. He gathers data from 10 students and fits a linear regression model to the data. The equation of the best fit line is given by \( y = 4.5x + 60 \), where \( y \) is the exam score and \( x \) is the number of hours studied. If a student studied for 8 hours, what exam score would the model predict for that student? Let's think step by step and output the final answer within \boxed{}.
