Answer:
17.75x + 5.25
165
x
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
165
Now, solve for x:
17.75x + 5.25
165
17.75x
159.75
x
9
So, x
9 is the answer, meaning 9 people or less can go to the amusement park.
