Question

How many friends at most can you invite to the school carnival?If it costs $8 per ticket, $3 for a one time processing fee, and the most you can spend is $45.

Answer 1

4 friends

Step-by-step 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:

`3+8t`

Since the most you can spend is $45, we have:

`\begin{gathered} 3+8t\leqslant45 \\ 8t\leqslant45-3 \\ 8t\leqslant42 \\ t\leqslant(42)/(8) \\ t\leqslant5.25 \end{gathered}`

You can invite a total of 4 friends (excluding yourself)

This means you can buy a maximum of 5 tickets.
