Answer 2

Answer:

Hello mate.

The population after two years will be 311040. The population 2 years ago was 138240

Step-by-step explanation:

Population 1 year before - less 20% increase

80/100 × 216000 = 2160 × 80 = 172800

Population 2 years before - less 20% increase

80/100 × 172800 = 80 × 1728 = 138240

2 years before the population was 138240
