This problem, an investor has two accounts, one at 9%, and one at 11%.
00:09
She has $8 ,000 less in the higher paying account.
00:14
And so if i call the 9 % x, that means the 11 % would be x minus $8 ,000, because it needs to be $8 ,000 less.
00:25
Now we know what her total interest is, so 0 .09x plus 0 .01, i'm sorry, plus 0 .0 plus 0 .0 plus.
00:36
Point one times x minus 8 ,000.
00:40
That's how much interest you gets on each of them.

We know that it gives us a total of 2010, so set that equal to 2010.
00:49
And then now we want to solve this.
00:52
So we have 0 .09x plus 0 .11x when we distribute that in...
