In 1980 231 million was the population and its growing at a rate of 1.03% per year.
Change 1.03% to a decimal: .0103, for the finding the total, it will be 1.0103
:
P = 231(1.0103^t); where t is the number of years from 1980, p in millions
:
Predict the pop. in the year 2025.
P = 231(1.0103^45)
enter 231(1.0103^45) in to your calc, your answer will be in millions (336.3)
