$5,000 is invested in two different accounts yielding 3% and 3.5% interest. the interest earned on the two accounts is $155.
how much money was invested at 3% interest?
$1,000
$3,000
$4,000

Equations:
x + y = 5000
3x + 3.5y = 15500

30x + 30y = 150000
30x + 35y = 155000

5y = 5000

y = $1000.00 (amt invested at 3.5%)

---
x = $4000.00 (amt. invested at 3%)
