Explanation:

Step1: Identify the relevant formula

To find the number of questions, we use the formula: Number of questions = Total points / Points per correct - answer.

Step2: Analyze the first - story

In the first story, she earns 4 points per correct answer and loses 3 points per incorrect answer, but we are only considering when she answers all questions correctly and has 12 points. The number of questions is calculated as $12\div4$, not $12\div3$.

Step3: Analyze the second - story

In the second story, she earns 3 points per correct answer and loses 4 points per incorrect answer. When she answers all questions correctly and has 12 points, the number of questions is calculated as $12\div3$.

Answer:

The second story (Chloe is participating in a math competition. She earns 3 points for every correct answer she submits, and she loses 4 points for every incorrect answer she submits. In the first round, Chloe answers all of the questions correctly to earn 12 points. How many questions does the first round have?)
