### Calculating the Maximum Number of People for an Amusement Park Visit

A group of friends wants to go to the amusement park. They have no more than $405 to spend on parking and admission. Parking costs $20, and tickets cost $38.50 per person, including tax. Which inequality can be used to determine \( x \), the maximum number of people who can go to the amusement park?

#### Inequality Options:
1. \( 38.5 + 20x \leq 405 \)
2. \( 20 + 38.5x \leq 405 \)
3. \( 38.5 + 20x \geq 405 \)
4. \( 20 + 38.5x \geq 405 \)

#### Explanation:
The total cost includes a fixed parking fee of $20 and the individual ticket cost of $38.50 per person. Therefore, the total cost for \( x \) people can be expressed as:
\[ 20 + 38.5x \leq 405 \]

This means that the correct choice is:
\[ \boxed{20 + 38.5x \leq 405} \]

### Detailed Breakdown:
- **Parking Cost:** $20
- **Ticket Cost per Person:** $38.50
- **Total Budget:** $405

To form the inequality, add the fixed parking cost to the product of the ticket cost per person and the number of people:
\[ 20 + 38.5x \leq 405 \]

This inequality can now be solved to find the maximum number of people \( x \) who can attend within the budget.
