The variation in size from year to year of a particular population can be
modelled by an exponential model with annual proportionate growth rate
0.1246. The size of the population at the start of the initial year is 360.
Choose the TWO options that give, as predicted by the model,
(a) the population size after 10 years;
(b) the number of years for the population size to reach at least 2500.
Options
A 15 B 17 C 20 D 24
E 849 F 1035 G 1165 H 1310

    population=360(1+r)^10=360*1.1246^10=1165

    check that.
