Answer:
n= 13.8 years
Step-by-step explanation:
First, we need to determine the daily interest rate:
Daily interest rate= 0.03 / 365
Daily interest rate= 0.000082
Now, using the following formula we can determine the number of days and years:
n= ln(FV/PV) / ln(1+i)
n= ln(13,000 / 8,600) / ln(1.000082)
n= 5,039 days
In years:
n= 5,039/365
n= 13.8 years
