.
T=amount at 3%; E=amount at 11%
.
T+E=$24000
T=$24000-E
.
0.03T+0.11E=$1520
0.03($24000-E)+0.11E=$1520
$720-0.03E+0.11E=$1520
0.08E=$800
E=$10000
ANSWER 1: $10000 was invested at 11%.
.
T=$24000-E=$24000-$10000=$14000
ANSWER 2: $14000 was invested at 3%.
.
CHECK:
0.03T+0.11E=$1520
0.03($14000)+0.11($10000)=$1520
$420+$1100=$1520
$1520=$1520
