Janie has $3. She earns $1.20 for every chore she does and can do fractions of chores. She wants to earn enough money to buy a cd for $13.50. Write an inequality to determine the number of chores, c, janie could do to have enough money to buy the cd

$1.20c + $3 ≥ $13.50     or     $1.20c ≥ $10.50

Step-by-step explanation:

So Janie has $3, and earns $1.20 for each chore. The number of chores she does is c, and she needs $13.50 for the cd. The amount of money she has after doing c number of chores is $1.20c + $3. In order for her to have enough money to buy the cd, the amount of money she has after doing c chores must be greater than or equal to $13.50. This can be written as the inequality:

$1.20c + $3 ≥ $13.50

This will work, but we can simplify this inequality by subtracting $3 from both sides of the equation.

$1.20c ≥ $10.50

$1.20c + $3 ≥ $13.50     or     $1.20c ≥ $10.50

I hope this helps. :)
