Question

Janie receives an allowance of \$3$3dollar sign, 3 per week. In addition, she can earn \$2$2dollar sign, 2 for each chore she does. This week, she wants to earn enough money to buy a CD for \$13$13dollar sign, 13. Janie can do fractions of chores.

Write an inequality to determine the number of chores, ccc, Janie must do this week to earn enough money to buy a CD.

3+2(c)=13
Identify which graph represents the solution set to this inequality.

Answer 1

The first thing we must do for this case is to define variables.

We have then:

c: number of chores that Janie sells

We write now the inequality that models the problem.

We have then:

`2c + 3\geq 13`

The solution of the inequality are all those points that belong to the numerical line shown. (See attached image)

Answer:

`2c + 3 \geq 13`
