Question

a city has a population of 350,000 people. suppose that each year the population grows 9%. what will the population be after 8 years

Answer 1

A = 350000e^.09(8)

= 350000e^.72

= 719,052, rounded off to nearest integer

or

A = 350000(1+.09)^8

= 697,397

depends on whether the population grows continuously, which seems more realistic, or just compounded once a year, less realistic

go with the 719.052 number. although the two solutions are not that far apart. about 700,000 rounded off to nearest 100 thousand, either way

A once a year increase in population would fit more with animals that have a once a year mating season.
