Answer:
It will take 18 years and 339 days to reach the goal.
Explanation:
Giving the following information:
You expect to receive $37,000 at graduation in two years. You plan on investing it at 9.5 percent until you have $172,000.
First, we need to calculate the time that will take 37,000 to reach 172,000. Then, we sum up to 2 years.
To calculate the number of years, we need to use the following variation of the final value formula:
FV=PV*(1+i)^n
Isolating n:
n=[ln(FV/PV)]/ln(1+r)
n=[ln(172,000/37,000)] / ln(1.095)= 16.93 years
To be more accurate:
0.93*365= 339 days
Now, we aggregate for 2 years.
It will take 18 years and 339 days to reach the goal.
