Janie receives an allowance of \$3$3dollar sign, 3 per week. In addition, she can earn \$2$2dollar sign, 2 for each chore she do
es. 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.

Identify which graph represents the solution set to this inequality.
1 answer:
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:
The solution of the inequality are all those points that belong to the numerical line shown. (See attached image)
