Answer:
If the interest rate is 10.5% the value of the investment at the time of retirement will be $1,189,576.02 higher.
Step-by-step explanation:
To calculate the future value, we need to use the following formula:
FV= PV*(1+i)^n
When i=8%
FV= 225,000*(1.08^25)
FV= $1,540,906.92
When i=10.5%
FV= 225,000*(1.105^25)
FV= $2,730,482.95
Difference= 2,730,482.95 - 1,540,906.92= $1,189,576.02
If the interest rate is 10.5% the value of the investment at the time of retirement will be $1,189,576.02 higher.
