Let's break down the costs involved with purchasing tickets for your family day out at the amusement park:
- Ticket price: $125 per ticket.
- Online processing fee: $5.75 per ticket.
- Parking fee: $20 total.
You have a total of $685 to spend.
To find out if you can buy tickets for your family of five, we first need to set up the total cost for buying \( t \) tickets, which includes both the ticket price and processing fee:
The total cost \( C \) for \( t \) tickets can be represented as:
\[ C = (125 + 5.75)t + 20 \]
Plugging in the values, the equation becomes:
\[ C = 130.75t + 20 \]
Now, we need to find the inequality to determine how many tickets can be purchased within your budget of $685:
\[ 130.75t + 20 \leq 685 \]
Now, let's solve the inequality step by step:
- Subtract $20 from both sides:
\[ 130.75t \leq 685 - 20 \] \[ 130.75t \leq 665 \]
- Divide both sides by $130.75 to solve for \( t \):
\[ t \leq \frac{665}{130.75} \] \[ t \leq 5.08 \]
Since \( t \) must be a whole number (you can't buy a fraction of a ticket), you can purchase at most 5 tickets.
Now to check the total cost for 5 tickets:
\[ C = 130.75(5) + 20 = 653.75 + 20 = 673.75 \]
You have:
\[ 673.75 \leq 685 \]
This means that you can afford 5 tickets with the money you have.
Conclusion
Based on the inequality \( 130.75t + 20 \leq 685 \), you have sufficient funds to purchase tickets for your family. You can buy a total of 5 tickets.
So the final answer is:
The correct inequality to determine how many tickets can be purchased is:
\[ 130.75t + 20 \leq 685 \quad \text{and yes, you can purchase 5 tickets.} \]
