Answer:
Value of investment after 21 years = $354,608.11
Step-by-step explanation:
The value of an amount invested at a certain rate of return for certain number of years where interest compounded annually is known as the future value.
The future value of an investment can be determined using the future value formula. This formula is stated below:
FV = PV × (1+r)^(n)
FV - Future Value , PV- Present Value, r-rate of return, n- number of years
For the first round of investment 15% for 7 years, future value would be:
FV = 14,800 × (1.15)^(7) = 39,368.29
Second round of investing 17% for 14 year, future value would be
FV = 39,368.29 × (1.17)^(14)= 354,608.11
Future Value =$354,608.11
Value of investment after 21 years = $354,608.11
