Question 1173740
<br>
a) 8.25% annual, compounded semi-annually:<br>
You want the periodic interest rate i, when applies 2 times a year, to give an annual interest rate of 8.25%, or 0.0825:<br>
{{{(1+r/2)^2 = 1.0825}}}<br>
{{{1+r/2) = 1.0825^(1/2)}}}
{{{i = r/2 = 1.0825^(1/2)-1}}}<br>
Use a calculator....<br>
n is the number of compounding periods. 6 years, 2 times a year, so n=6*2=12.<br>
b) 8.25% annual, compounded daily:<br>
Same calculations as above, with a different number of compounding periods per year.<br>
The exact answers depend on whether you use 365 days in a year or, as is often done, the rounded number of 360.<br>
Since I don't know which you want to use, and since the calculations are exactly the same as for the first case, I leave the calculations to you.<br>
