Solve the problem.A population of algae consists of 4000 algae at time t = 0. Conditions will support at most 300,000 algae. The rate of growth of algae is proportional both to the number present (in thousands) and to the difference between 300,000 and the number present (in thousands). Given that the constant of proportionality is 0.01, a differential equation is   Approximate the number of algae present when t = 2, using h = 0.5.

A. about 128 thousand
B. about 133 thousand
C. about 141 thousand
