ridiculously high growth rate of 12% after one year. Unfortunately, the growth rate
proved to be too much, leading to water and air pollution problems and an
infrastructure (streets, etc.) not prepared for such rapid growth. So, during year 2,
Vibrioville's growth rate dropped to only 0.4%. Therefore, after 2 years, Vibrioberg
added ____(1)___ people, and Vibrioville added ___(2)____ people to their
respective populations. - Answer- (1) 1,278 and (2) 1,245
