A reviewer can close 7 items per day and has 28 open submittal comments. How many days are needed?
Correct Answer
C) 4 days
Backlog duration is 28 / 7 = 4 days.
Why This Is the Correct Answer
Backlog duration is 28 / 7 = 4 days.
Why the Other Options Are Wrong
Option A: 3 days
document review backlog, choice a: 3 days backs into 0.43 when divided by 7; the accepted setup gives 0.57 on that same base.
Option B: 5 days
document review backlog, choice c: 5 days backs into 0.71 when divided by 7; the accepted setup gives 0.57 on that same base.
Option D: 196 days
document review backlog, choice d: the number 196 days comes from 7 x 28.
Memory Technique
Store document review backlog with its last math move; nearby answers are usually unfinished versions of 4 days.
Reference Hint
Open Construction Jobsite Management, 5th Ed. (2024); use by topic index - documentation / submittals / RFIs / closeout to confirm that Backlog duration is 28 / 7 = 4 days.
