Carter is playing a video game he needs to score more than a hundred points to move on to the next level write an inequality to show how many points carter needs to earn

The first thing you should do in this case is to define the necessary variable.
 We have then:
 x: number of points to go to the next level.
 We write the inequality based on the following fact:
 "I need to score more than a hundred points"
 The inequation is:
 x> 100
 
 an inequality to show how many points Carter needs to earn is:
 x> 100

These are the multiples of 15 but what you are probably asking or what are the factors of 15
