A group of friends wants to go to the amusement park. They have no more than $165
Oksi-84 [34.3K]

Answer:

17.75x + 5.25 \leq 165

x \leq 9

Step-by-step explanation:

The total cost can be represented by 17.75x + 5.25, where x is the number of people.

They can only spend a maximum of $165, so a less than or equal sign has to be used.

The inequality will be 17.75x + 5.25 \leq 165

Now, solve for x:

17.75x + 5.25 \leq 165

17.75x \leq 159.75

x \leq 9

So, x \leq 9 is the answer, meaning 9 people or less can go to the amusement park.
