All right, so to answer this question, we need to use a formula that gives us the effective annual rate, which is equal to 1 plus the nominal rate divided by the number of compounding periods raised to that power minus 1.
00:14
So for a, when the interest is compounded monthly, we're given our effective, and remember, this is the effective annual rate, which is equal to 1 plus 0 .05, which is our nominal rate of 5%.
00:34
Divided by 12 periods raised to the 12 power minus 1.
00:39
And if you put this in your calculator, you are given an effective rate of 0 .0 -5116 or 5 .116%.
00:58
Remember, this is annually.
01:00
So because we're already factoring in the effect of compounding, we can just divide this by 12 to get the effective monthly rate, which is 0 .1 .5%.
01:12
0 .4 to 6 % monthly.
01:16
Now with b, when we are compounding daily, remember that this is just the same equation...
