maths compound interest
posted by minerva .
find the compund interest on $2500 for one year at 4% per annum compounded halfyearly.
which of these is correct?
$2500(1 + 0.04)^2
or
$2500(1 + 0.02)^2
The second one. 2500(1+.02)^2
Since the interest is compounded semiannually you have to divide the annual rate of 4% by 2.
PS, the actual compound interest, which your question asks for, would really be 2500(1+.02)^2  2500
