Let's start by writing down what we know.
00:03
50 ,000 is our amount to invest.
00:13
X is the amount invested in the bond.
00:22
She's going to invest in a bond and a cd, so that's y be the amount invested in the cd.
00:34
And we want to know how much that is.
00:36
So our problem here is to find y.
00:41
Now we have two variables.
00:45
And in order to solve this, we need to have come up with two equations so we can do that.
00:52
50 ,000 will be x plus y because our total investment is what we invest in the bond and in the cd.
01:02
We want to earn 6 ,000.
01:07
Well our earnings are 15 % on every dollar invested in the bond, so 0 .15 times the number of dollars in the bond, and we earn 7 % on each dollar in the cd...
