Given that Janie has $3. She earns $1.20 for each chore she does and can do fractions of chores. She wants to earn enough money to buy a CD for $13.50.

we have to find the fraction of chores Janie did to earn total of $13.50

Let the fraction of chores is x which Janie wants to earn enough money to buy a CD for $13.50.

Total money=$3+$1.20(fraction of chores)

$13.50=$3+$1.20(x)

$13.50-$3=$1.20(x)
