Answer:
4 friends
Explanation:
One time processing fee =$3
Cost per ticket = $8
Let the number of tickets = t
The total amount spent for t tickets will be:
[tex]3+8t[/tex]Since the most you can spend is $45, we have:
[tex]\begin{gathered} 3+8t\leqslant45 \\ 8t\leqslant45-3 \\ 8t\leqslant42 \\ t\leqslant\frac{42}{8} \\ t\leqslant5.25 \end{gathered}[/tex]You can invite a total of 4 friends (excluding yourself)
This means you can buy a maximum of 5 tickets.
