Quick answer: shift rate = base + differential. A 10% night differential on 24.00 is 2.40 more, 26.40 an hour; 36 hours at that rate is 950.40, of which 86.40 is the differential.
How shift differentials work
A differential is added to the base rate for less popular shifts: 10% on a 24.00 base is 2.40 more, 26.40 an hour. A flat differential adds the same amount whatever the base. Federal rules count the differential in the regular rate (29 CFR 778.207), so overtime on those hours is at least 1.5 x the higher shift rate.

Questions
What is a typical night shift differential?
There is no legal minimum; it is set by the employer or a union contract. Nurses and factory workers often see 10 to 15% or a flat amount per hour.
