A group of friends wants to go to the amusement park. They have no more than $225 to spend on parking and admission. Parking is $5, and tickets cost $20 per person, including tax. Write and solve an inequality which can be used to determine the number of people who can go to the amusement park.

We want to write and solve an inequality to determine the number of people who can go to the amusement park.

The solution is p ≤ 11

The friends have a maximum of $225 to spend.

The parking is independent of p, the number of friends, and it costs $5, discounting that we get: $225 - $5 = $220

Each ticket costs $20, so the cost for p people is:

p*$20

And this must be equal to or smaller than $220, then we get the inequality:

p*$20 ≤ $220

To solve it for p, we need to divide both sides by $20, we will get:

p*$20/$20 ≤ $220/$20

p ≤ 11

This inequality gives the number of people that can go to the amusement park.

Hope this helps you :D

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
