Required
Write an expression for Andrew
3 fewer means that we subtract 3 from Paul's number of DVDs.
i.e.
![Andrew = Paul - 3](https://img.qammunity.org/2022/formulas/mathematics/high-school/lksrsnpyyu8n9zyj1b4pxohdmh7u8w79a3.png)
Substitute k for Paul
![Andrew = k - 3](https://img.qammunity.org/2022/formulas/mathematics/high-school/vrmevtb6gsot4mn0du4lkfthfctnpak4i1.png)
