Answer:
18.7 years
Step-by-step explanation:
This is a compound interest problem and the following variables have been given;
Principal = 4000; this is the amount o be invested
APR = 9%; this is the compound interest to be earned
Accumulated amount = 20,000
We are required to determine the duration in years. We apply the compound interest formula;


The next step is to introduce natural logarithms in order to determine n;

The number of years required is thus 18.7 years
100.47 because: 33.3+1.4 =34.7
785+1=786
34.7log(786)=100.47
The greatest common factor is 2
If

is left, that means

was spent. So

of the total amount is equal to 39.. Let's say x to the total amount.
