Question

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.

Answer 1

Number of chores done by Janie are 5.

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
`\geq`13

⇒ 2c
`\geq` 13-3

⇒ c
`\geq` 10÷2

⇒ c
`\geq` 5
