how to summarize finding for b

An observation indicates that the frog population Q(t) in a small pond is 25 initially and
satisfies the logistic equation
Q(t)' = 0.0225Q(t) – 0.0003Q(t)²,
(with t in months.)
a. Apply Modified Euler's method together with any computer program to approximate the
solution for 10 years. Use the step size of h = 1 and then with h = 0.5
b. Find out the percentage of the limiting population of 75 frogs has been attained after 5
years and after 10 years
c. Summarize your findings in (b)
