Linear Equation Word Problems

Question

Abbeville is a small town that has been steadily growing since 1960. Use the table below to create a linear equation the estimate Abbeville's population over time. What will the population be in 2016  if the growth remains constant?

 

       Year:    1960      1970    1980     1990     2000

Population:    60          76       92        108       124

 

a.155

b.145

c.144

d.150     

Answer 1

Examine the data...for each increase of ten years, is there a constant change of population?

 

To go from year 2000 to year 2010, what would the change be?

 

Then to go from 2010 to year 2016, you'd increase the 2010 population by 0.6 of the constant decade change, because that's just 60% of a new decade.

 

Clear?
