An investor invests $23 ,000.
00:05
One in a bond that pays 4%, another, and one that pays 2%.
00:10
Now, we don't know how much is in either one.
00:13
We can't assume it's the same amount.
00:15
So let's say we had x amount in this bond, then 23 ,000 minus x would be the amount in this bond.
00:23
So how does he make money? he makes interest based on the principle, the rate, and the time.
00:29
Well, we're only dealing with the year, so we don't need to be.
00:31
The time.
00:32
So my rate interest here is going to be 0 .04 times x.
00:37
The interest here, 0 .02, comes 23 ,000 minus x...
