How long will it take for 74,500 to accumulate to 101,000 if the
interest rate is 10.5 % compounded quarterly?
~~~~~~~~~~~~~~~
For the amount of $74,500, compounded quarterly, the future value formula is
Future Value =
where n is the number of quarters.
Therefore, an equation to find "n" is
101000 =
Divide both sides by 74500
= ,
or
1.355705 = .
Take logarithm base 10 of both sides
log(1.355705) = n*log(1.02625)
and find "n" using your calculator
n = = 11.745 quarters.
Finally, round this value 11.745 to the nearest greater integer 12,
in order for the bank was in position to make the last compounding.
ANSWER. 12 quarters, or 12/4 = 3 years.
Solved.
