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.

3+2(c)=13
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)

Answer:
Step-by-step explanation:
From the table given in the question,
x y Difference Ratio
1 12 - -
2 36 36-12 = 24
3 108 108-36 = 72
4 324 324-108 = 216
5 972 972-324 = 648
There is a common ratio of 3 in each successive term.
Therefore, data given in the table will represent an exponential function.
For a point
------(1)
For another point of the table ,
--------(2)
Equation (2) divided by equation (1)
From equation (1),
Therefore, exponential function will be,
