**Damon**, Sunday, November 30, 2008 at 7:57pm.10 x + .05 (30,000-x) = 2,300

10 x + 5 (30,000-x)= 230,000

2 x + (30,000 - x ) = 46,000

x + 30,000 = 46,000

you take it from there

**drwls**, Sunday, November 30, 2008 at 8:00pmAssume that the money was left on deposit for one year. They should have told you that.

If x was invested at 10%, 30,000- x was invested at 5%

x * 0.10 + (30,000 -x) * 0.05 = 2300

0.1 x + 1500 - .05x = 2300

0.05 x = 800

x = 16,000 (invested at 10%)

(30,000 - x) = 14,000 invested at 5%
