The future value and present value equations also in finding the interest rate and the number of years that correspond to present and future value calculations. if a security currently worth $12,800 will be worth $16,843.93 seven years in the future, what is the implied interest rate the investor will earn on the security—assuming that no additional deposits or withdrawals are made? 4.00% 0.19% 3.20% 7.60%

i=4%

Explanation:

this problem is possible to solve applying the principle of future value, keep in mind the next formula:

where FV is future value, PV is the present value, i is the periodic interest rate and n is the number of periods. So applying to this particular problem we have:

the difference here is that we must solve n so we can do:

so i=4%
