Let's analyze the given table representing the number of files and the corresponding storage space used:
[tex]\[
\begin{tabular}{|c|c|}
\hline
\text{Number of Files} & \text{Space Used (Mb)} \\
\hline
10 & 15 \\
\hline
20 & 30 \\
\hline
30 & 45 \\
\hline
40 & 60 \\
\hline
50 & 75 \\
\hline
\end{tabular}
\][/tex]
We need to determine the best statement that describes the relationship between the storage space and the number of music files.
### Step-by-Step Analysis:
1. Identify the Trend:
- For 10 files, the space used is 15 Mb.
- For 20 files, the space used is 30 Mb.
- For 30 files, the space used is 45 Mb.
- For 40 files, the space used is 60 Mb.
- For 50 files, the space used is 75 Mb.
2. Observe the Changes:
- From 10 to 20 files, space increases from 15 to 30 Mb.
- From 20 to 30 files, space increases from 30 to 45 Mb.
- From 30 to 40 files, space increases from 45 to 60 Mb.
- From 40 to 50 files, space increases from 60 to 75 Mb.
3. Consistent Increase in Space:
- Each time the number of files increases by 10, the space used increases by 15 Mb.
4. Determine the Relationship:
- The relationship observed shows a direct proportionality: as the number of files increases, the storage space used also increases.
### Final Conclusion:
Based on the data provided in the table, the best statement that describes the relationship between storage space and the number of music files is:
- As the number of files increases, the storage space used increases.
Therefore, the correct answer is: "As the number of files increases, the storage space used increases."
