The Late Finish (LF) day is calculated by adding the Duration to the Late Start (LS) and then subtracting 1 to account for the fact that the Late Start is the first day of the activity.

Formula: LF = LS + Duration - 1

• Late Start (LS) = 5
• Duration = 7

Calculation: LF = 5 + 7 - 1 = 11

The Late Finish (LF) day is day 11.
