Answer:
70% of the reports will take 525 minutes (8 hours, 45 minutes) to file.
Step-by-step explanation:
Given;
total number of Meredith's report, N = 10
average time taken for each report to be filed is, t = 75 minutes per report
let the total time for the 10 reports = T
[tex]\frac{T}{N} = t\\\\T = N*t \\\\T = 10 *75\\\\T = 750 \ minutes[/tex]
The total time for the 10 reports is 750 minutes.
Time taken to file 70 % of 10 reports = (0.7 x 10) x (75 mins)
= 0.7 x 750
= 525 minutes (8 hours, 45 minutes)
Therefore, 70% of the reports will take 525 minutes (8 hours, 45 minutes) to file.
