Just curious why for part(i), not find the range of P when dp/dt > 0, but use the second derivative> 0 instead

My bad, my interpretation of the question was wrong. It should've been the first derivative.
I) dP/dt = 0.02P (100-P)
0.02P (100-P) > 0
P (100-P) > 0

[Draw Number line]

ANS: 0< P < 100

Please take note of the change.Thanks! ;))
