IF YOU ANSWER THIS QUESTION I WILL GIVE YOU 5 THUMBS UP. THE QUESTION IS THE POPULATION OF CERTAIN SPECIES IS X NOW . IT BECOMES Y ITSELF AFTER ONE WEEK . WHAT WILL BE ITS POPULATION AFTER TWO WEEKS ?

Answer 1

Initial population = x

Population after 1 week = y

∴Increase in population in 1 week = y - x
