if japan's population is 128 million. if the population decreases by 0.2% every year, what will the population be in 2040?
2040 - 2017 = 23 years
Present population = 128 M
Future population =?
FP = 128 x [1 + R]^N
FP =128 x 0.998^23
FP =128 x 0.955....
FP =122.24 Million - expected Japan's population in 2040.
