The population of less-developed countries in mid-2007 of 4086 billion expected to grow at 1.8% per year, If this growth rate continues until mid-2025, what will be the size of the population then?
let t be year.
One question to explore, is the exponential model to use for population.
Population(2025)=4086e^.018*18=you do it.
