Korolek [52]

Since, population of species A is represented by : P=2^{x} +19

Let us find the population of species A, at the end of week 1:

i.e., x = 1

i.e., P(1)=2^{1} +19

i.e., P(1)=2 +19

i.e., P(1)=21


Also, since population of species B is represented by : P=3^{x} +18

Let us find the population of species B, at the end of week 1:

i.e., x = 1

i.e., P(1)=3^{1} +18

i.e., P(1)=3 +18

i.e., P(1)=21


Thus, at the end of 1 week, species A and species B will have the same population.

Hence, option D is correct.
