Notice that the population increases by 16 every 10 years.
If t = 0 represents 1960, then you need the equation of a line with y-intercept 60 and slope m = 16/10 = 1.6.
If P(t) represents the population of the town, then
P(t) = 1.6t + 60.
To estimate the population in 2016, you would set t = 2016 - 1960 = 56 and calculate it from the equation.
This is left to you. You can post a reply if you need more help.

Chris,
The population actually INCRESES over time. The town gains 16 new residents every decade. This means it changes at a rate of 1.6 persons per year, and the rate is constant. This is the reason why you can find a LINEAR equation to model the population.
