The poaching model for Species Y is Y' = 0.001231 Y (1 - Y) - 0.002231 where the variable Y represents the population of Species Y and Yo = 1857 when t = 0. Use Euler's method with At = 0.2, to approximate the population of Species Y (to the nearest integer) when t = 5. O a) 227 O b) 106 O c) 207 O d) 135 O e) 262
