As we already have the model that describes the change of the population in Italy in terms of the years that have elapsed, we only have to replace the conditions that are requested in that equation.
 Therefore to find the population of Italy in the year 2000 (t = 10 years)  substitute t = 10 in the equation and have:
 
  million people
 million people
 To find the population of Italy in 2008 (t = 18 years)
 substitute t = 18 in the equation and have:
 
  million people
 million people
 To predict the population in Italy for 2015 and 2020 with this model, we substitute in the equation t = 25 and t = 30
 t = 25
  
  million people
 million people
  t = 30
  
  million people
 million people
 
        
             
        
        
        
For this case we have an equation of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: growth rate
 t: time
 The given equation is:
 a = 1300 (1.02) ^ 7
 Where,
 b = 1.02
 It represents a growth of 2% on the initial amount.
 Answer:
 1.02 represented in this equation a growth of 2% on the initial amount.
