The population of a certain city increases by 2.3% per year. Assuming the population was 7.6 million, what is the population expected to be by 2010? what was the population in 1980?
I assumed the base year is 2017 ; because the time is not mentioned So 2017-2010=7 years P=7,600,000÷(1+0.023)^(7) P=6,481,628.81 2017-1980=37 P=7,600,000÷(1+0.023)^(37) P=3,276,537.51
