Question

The population of Williston is currently 21,200 people. If the population

increases at an average rate of 415 people per year, which equation could
be used to find the approximate number of years it will take for the
population to reach 27000 people?

Answer 1

`21200 + 415(y)`

`27000 = 21200 + 415(y)`

`27000 - 21200 = 21200 - 21200 + 415(y)`

`5800 = 415(y)`

`(5800)/(415) = (415(y))/(415)`

`13.9759..... = y`

`it \: will \: take \: about \: 14.0 \: years`
