Three different types of candy that cost $1.29, $1.79, and
$2.39 per pound are to be mixed to produce 14 pounds of
candy worth $23.86. If there is to be twice as much of the
$1.29 candy as the $2.39 candy, how much of each type
should be mixed together?
let x=pounds of 2.39 candy
2x=pounds of 1.29 candy
14-3x=pounds of 1.79 candy
Pounds to be mixed:
$2.39 candy: 3 pounds
$1.29 candy: 6 pounds
$1.79 candy: 5 pounds
