To solve the inequality \(15y - 9 < 36\), we will follow a step-by-step process.

1. Start with the given inequality:
[tex]\[ 15y - 9 < 36 \][/tex]

2. Add 9 to both sides of the inequality to isolate the term with \(y\) on the left side:
[tex]\[ 15y - 9 + 9 < 36 + 9 \][/tex]
This simplifies to:
[tex]\[ 15y < 45 \][/tex]

3. Divide both sides by 15 to solve for \(y\):
[tex]\[ \frac{15y}{15} < \frac{45}{15} \][/tex]
Simplifying, we get:
[tex]\[ y < 3 \][/tex]

Thus, the solution set of the inequality \(15y - 9 < 36\) is:
[tex]\[ y < 3 \][/tex]

Therefore, the correct answer is:
[tex]\[ \boxed{y < 3} \][/tex]
