![8-n](https://img.qammunity.org/2023/formulas/mathematics/college/x1k93w4j5nreuktnecse1d4gnil8n8bf89.png)
Because to the initial amount of 8, we subtract n.
Then she had 3 plants left, this is described by the equation:
![8-n=3](https://img.qammunity.org/2023/formulas/mathematics/college/7w4ne20j4vti7uselhoh6tky1ccqghhob2.png)
Which is the second option.
