Answer:
The solution in the attached figure
Step-by-step explanation:
we have
-----> inequality A
The solution of the inequality A is the shaded area at left of the solid line x=-3
----> inequality B
The solution of the inequality B is the shaded area below the solid line 
The solution of the system of inequalities is the shaded area between the two solid lines
using a graphing tool
see the attached figure
Part A: 680-960d= 52,000
Part B: Answer $54.875
Do inverse operation
Add 680 to both sides
Then divide 960 to both sides
