Question 955462
F=part invested at 14%; E=part invested at 11%
F+E=$4000
E=$4000-F
0.11E+0.14F=$482 Substitute for E.
0.11($4000-F)+0.14F=$482.
$440-0.11F+0.14F=$482 Subtract $440 from each side.
0.03F=$42 Divide each side by 0.03.
F=$1400 ANSWER 1: $1400 was invested at 14%.
E=$4000-$1400=$2600 ANSWER 2: $2600 was invested at 11%

0.11E+0.14F=$482 
0.11($2600)+0.14($1400)=$482 
$286+$196=$482
$482=$482
