Question

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?

Answer 1

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
