For this case we have the following equation: P (t) = P * (1 + r / n) ^ (n * t) Where, P: initial investment r: interest rate n: periods Substituting values: 3 * 2500 = 2500 * (1 + 0.06 / 4) ^ (4 * t) Rewriting: 3 = (1,015) ^ (4 * t) Clearing t: log1.015 (3) = log1.015 ((1.015) ^ (4 * t)) 4 * t = log1.015 (3) t = (1/4) * log1.015 (3) t = 18.45 years Answer: the money will need to be invested 18.45 years for that amount to triple
