Answer:
The answer/volume is 576
Explanation:
I used a calculator for the volume online
10 × 75 = 750 minutes to file 100% of the files. (Approximately 12.5 hours)
= 0.7
70% of these files = 750 × 0.7 = 525 minutes.
Converting 525 minutes into hours, Jan would to take 8.75 hours to file 70% of the files.
