An activity had 9 days of total float and a delay consumes 4 days. How much float remains?
Correct Answer
D) 5 days
Remaining float is 9 - 4 = 5 days.
Why This Is the Correct Answer
Remaining float is 9 - 4 = 5 days.
Why the Other Options Are Wrong
Option A: 4 days
float consumption, choice a: 4 days uses the wrong side of the schedule subtraction or omits one duration component.
Option B: 9 days
float consumption, choice c: 9 days is wrong because 9 days uses the wrong side of the schedule subtraction or omits one duration component.
Option C: 13 days
float consumption, choice d: 13 days uses the wrong side of the schedule subtraction or omits one duration component.
Memory Technique
Remember float consumption as "base, adjustment, final unit"; the last unit should read 5 days.
Reference Hint
Open Construction Jobsite Management, 5th Ed. (2024); use by topic index - duration / float / baseline / updating / variance to confirm that Remaining float is 9 - 4 = 5 days.
