Question 1069930
Total to invest: 30,000
One amount at 4%, let the amount be x: 0.04x
another amount at 6%, this amount will be 30,000-x
interest earned per year: 4,620/3 =  1540
---------------------------------------
0.04x+0.06(30,000-x) = 1540
0.04x+1,800-0.06x = 1540
-0.02x = -260
x = 13,000 this is the amount invested at 4%
30,000-13,000 = 17,000 this is the amount invested at 6%
