Suppose that 200 fish are introduced into a protected lake. The fish population can be approximated by P= 200+40 t/ 1+0.
Suppose that 200 fish are introduced into a protected lake. The fish population can be approximated by P= 200+40 t/ 1+0.05 t , with t being the time in years since the fish were introduced into the lake.
How is this found to be 500+25x=200+40x? How was the 25x calculated?
