Answer:

  44.5 years

Step-by-step explanation:

Each year the population is multiplied by 1 +2.5% = 1.025. In n years, the population is multiplied by 1.025^n. We want to find n such that this multiplier is 3.

  3 = 1.025^n

  log(3) = n·log(1.025)

  n = log(3)/log(1.025) ≈ 44.5 . . . . years to triple the population
