Answer:
The correct answer option is C. y < 3.
Explanation:
We are given the following inequality and we are to solve it in terms of y and find its solution set:
![15y - 9 < 36](https://img.qammunity.org/2020/formulas/mathematics/high-school/2n6fu5fyng29ytzwoqfg0szikpfyndtrz7.png)
Taking the constants to one side of the inequality and variable at the other side to get:
![15y < 36 + 9](https://img.qammunity.org/2020/formulas/mathematics/high-school/avc6ry0ase929qufvuatvfcwochf78q7j7.png)
![15y < 45](https://img.qammunity.org/2020/formulas/mathematics/high-school/slhfxlxow76yjsxeoy2n8drei8jv2o5hjg.png)
![y < \frac {45} {15}](https://img.qammunity.org/2020/formulas/mathematics/high-school/fzdj3jg0q1vw1yi65d35g5tecjzfcuy5ew.png)
