Answer:
36.04 % decrease
Step-by-step explanation:
given initial daylight hours: 15.01 hrs
final daylight hours(5 months later) : 9.60 hrs
change in daylight hours = final - initial = 9.6 - 15.01 = -5.41
(or 5.41 hour decrease)
percentage decrease = (change in daylight hours / initial daylight hours) x 100%
= (5.41 / 15.01) x 100%
= 36.04 % decrease
