A group of friends wants to go to the amusement park. They have no more than $235 to spend on parking and admission. Parking is $7.50, and tickets cost $32.50 per person, including tax. Write and solve an inequality which can be used to determine xx, the number of people who can go to the amusement park.
32.50x + 7.50 \leq 235
32.50x \leq 227.50
x \leq 7
Therefore, the group of friends can have a maximum of 7 people go to the amusement park with their budget.
