To determine which statement is true about Debi's data, we can analyze the steps she takes for each lap.

From the data provided in the table, we have the following steps for each lap:

- 0 laps: 1,875 steps
- 1 lap: 4,300 steps
- 2 laps: 6,725 steps
- 3 laps: 9,150 steps
- 4 laps: 11,575 steps

To find the number of steps per lap, we can calculate the difference in steps between each consecutive lap:

1. From lap 0 to lap 1:
\(4,300 - 1,875 = 2,425\) steps.

2. From lap 1 to lap 2:
\(6,725 - 4,300 = 2,425\) steps.

3. From lap 2 to lap 3:
\(9,150 - 6,725 = 2,425\) steps.

4. From lap 3 to lap 4:
\(11,575 - 9,150 = 2,425\) steps.

From this analysis, we can conclude that Debi walks **2,425 steps per lap** around the mall.

Now, let's evaluate the statements:

1. "Debi walks 1,875 steps per lap around the mall." - **False**
2. "One lap around the mall is equal to 2,425 steps." - **True**
3. "One lap around the mall is equal to 4,300 steps." - **False**
4. "Debi walks 6,175 steps per lap around the mall." - **False**

Thus, the correct statement is: **"One lap around the mall is equal to 2,425 steps."**
