Given:
Cost of four lines = $125
Cost of each additional line = $15
Jason wants to spend at most $200 per month on cell phone expenses.
To find:
The inequality for the given situation.
Solution:
Let be the number of additional line.
Cost of one additional line = $15
Cost of additional line =
Total cost = Fixed cost + Addition cost
=
It is given that Jason wants to spend at most $200 per month on cell phone expenses. It means the total cost must be less than or equal to 200.
Therefore, the correct option is C.

Step-by-step explanation:
<u><em>Verify the solution of each case</em></u>
case 1) we have
Divide the compound inequality into two inequalities
---> solution is the interval (-∞,4]
---> solution is the interval [-4,∞)
The solution of the compound inequality is
[-4,∞) ∩ (-∞,4] ----> [-4,4]
case 2) we have
Divide the compound inequality into two inequalities
---> solution is the interval (-∞,-1]
---> solution is the interval [-2,∞)
The solution of the compound inequality is
[-2,∞) ∩ (-∞,-1] ----> [-2,-1]
case 3) we have
---> solution is the interval (-∞,-1]
or
---> solution is the interval [0,∞)
The solution of the compound inequality is ----> (-∞,-1] ∪ [0,∞)
case 4) we have
---> solution is the interval (-∞,3]
or
---> solution is the interval [-1,∞)
The solution of the compound inequality is
(-∞,3] ∪ [-1,∞) ---->(-∞,∞)
