Final answer:
The equation that describes the situation is 50-3x=2.
Step-by-step explanation:
The equation that best describes the situation is option A, 50-3x=2.
Here's how we can arrive at this equation:
- Jack's mother gave him 50 chocolates.
- Jack gave 3 chocolates to each of his friends.
- Jack had 2 chocolates left.
To represent the number of friends at Jack's party as 'a', we can set up the equation: 50 - 3a = 2.
This equation shows that Jack started with 50 chocolates, subtracted 3 chocolates for each friend, and ended up with 2 chocolates remaining.
Therefore, the correct equation that describes the situation is A. 50-3x=2.
