The fraction of chores which Janie wants to earn enough money to buy a CD for $13.50 are 8.75~9 chores
Step-by-step explanation:
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)
x=8.75~9
Hence, the fraction of chores which Janie wants to earn enough money to buy a CD for $13.50 are 8.75~9 chores
