Oliver's Study Score Prediction

Oliver is studying the relationship between the number of hours he studies for his math test and the score he receives. He finds that for every hour he studies, his score increases by 5 points. He starts with a score of 60 points when he studies 0 hours. This relationship can be modeled by the linear function:

$$S(x) = 5x + 60$$

where $$S$$ represents the score and $$x$$ represents the number of hours studied. If Oliver studies for 3 hours, what will be his score?
