The total investment of 23,000 was divided into two accounts paying 4% and 9% interest respectively. (Assuming simple yearly interest.)

The total interest is 1320.00

Let x be the amount invested at 4%, then 23000-x is invested at 9%. The total interest earned is the sum:

`.04x+.09(23000-x)=1320`

`.04x+2070-.09x=1320`

`.05x=750`

`x=15000`

------------------------------------------------------------------

15,000 was invested at 4% and 8,000 was invested at 9%
