Let x be the number of people invited to the party; then, the inequality is
![55+12.5t\le150](https://img.qammunity.org/2023/formulas/mathematics/college/wdm447d4hmkinl9bep6gkyeab1qthjqlfg.png)
Solving for t,
![\begin{gathered} \Rightarrow12.5t\le95 \\ \Rightarrow t\le7.6 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/dlm53ox7ewr8gkibxrfpu4gp6cii3plyio.png)
This is the solution to the inequality (despite the fact that Harper cannot invite more than 7 people). Then, the graph of the solution of the inequality is
The point has to be on the 7.6 mark (not a hollow point), and the arrow points towards the negative direction.
