Answer:
12 years
Step-by-step explanation:
From the formula;
A = P(1 + r)^n
A = Amount = $2733.19
P = Principal = $2150
r = rate = 2%
n = time in years = ???
2733.19 = 2150(1 + 0.02)^n
2733.19/2150 = (1 + 0.02)^n
1.27 = (1.02)^n
Taking logarithm of both sides
log 1.27 = n log 1.02
n= log 1.27/log 1.02
n= 0.1038/0.0086
n = 12 years
