Explanation:
Given: A thrill ride at an amusement park holds a maximum of 12 people per ride.
To find :
a. An inequality that you can use to find the least number of rides needed for 15,000 people.
b. Then find the least number of rides needed for 15,000 people.
Solution :
Let x represent the number of rides.
a) A ride holds maximum of 12 people = 12x
To find an inequality of the least number of rides needed for 15,000 people.
The equation is
![12x = 15000](https://img.qammunity.org/2020/formulas/mathematics/high-school/bm464is6cb9mkqvznbg6yajbhe7pz5i0ac.png)
b) Find the least number of rides needed for 15,000 people.
Solve the equation,
