Janie receives an allowance of \$3$3 per week. in addition, she can earn \$2$2 for each chore she does. this week, she wants to earn enough money to buy a cd for \$13$13. janie can do fractions of chores. write an inequality to determine the number of chores, cc, janie must do this week to earn enough money to buy a cd.

Number of chores done by Janie are 5.

Step-by-step explanation:

Janie's allowance per week is $3.

For each chore she earns $2.

Now we assume that number of chores in a week she does = c

Then total earning from chore = $2 × c

So for the purchase of CD total earning this week inequality will be

⇒ 3 + 2c 13

⇒ 2c 13-3

⇒ c 10÷2

⇒ c 5
