Answer:
The inequality which represents the model for this situation is 
.
Step-by-step explanation:
Let Mr. Garcia has 
number of desks initially.
He has been asked to give 
desks to Mrs. Johnson.
Also, he needs to keep at least 
desks for his students.
So, after giving desks to Mrs. Johnson from the total number of desks he has, he must have at least desks for his students.
Therefore, the inequality is: .
Hence, the inequality which represents the model for this situation is .
Here is a substitution problem. By saying c is 4, we can replace anywhere we see c with the number 4.
c = 4
4c - 7.8
= 4(4) - 7.8
= 16 - 7.8
= 8.2
