Question 954181
Not enough info given: we know the second account pays less than the first, so let's use 2% as an example
F=amount at 4%; T=amount at 2%
F+T=22000
T=22000-F
0.04F+0.02T=810 Substitute for T
0.04F+0.02(22000-F)=810
0.04F+440-0.02F=810 Subtract 440 from each side.
0.02F=370 Divide each side by 0.02
F=18500 ANSWER 1: 18500 was invested at 4%.
T=22000-18500=3500 ANSWER 2: 3500 was invested at 2%.
CHECK:
0.04F+0.02T=810
0.04(18500)+0.02(3500)=810
740+70=810
810=810
