The population of a town is increasing by

611 people per year. State whether this growth is linear or exponential. If the population is 1800 today, what will the population be in

five years?

The growth is linear, in five years the population will be 4,855. The equation of this problem is y=611x+1800, with the y being the total population and x the number of years, replace the x with 5 and then solve to get 4,855.
