Let's break down the problem step-by-step:
1. Initial Number of Marbles:
- Chris starts with 18 marbles.
- Kevin starts with 15 marbles.
2. Chris Gives Half of His Marbles to Kevin:
- Half of Chris's marbles is calculated as [tex]\( \frac{18}{2} = 9 \)[/tex].
- Chris gives these 9 marbles to Kevin.
3. New Number of Marbles for Kevin:
- Initially, Kevin had 15 marbles.
- After receiving 9 marbles from Chris, Kevin now has [tex]\( 15 + 9 = 24 \)[/tex] marbles.
4. New Number of Marbles for Chris:
- Initially, Chris had 18 marbles.
- After giving away 9 marbles to Kevin, Chris now has [tex]\( 18 - 9 = 9 \)[/tex] marbles.
5. Difference in Marbles Between Kevin and Chris:
- Now, Kevin has 24 marbles and Chris has 9 marbles.
- The difference in the number of marbles between Kevin and Chris is [tex]\( 24 - 9 = 15 \)[/tex].
So, Kevin has 15 more marbles than Chris.
