Answer:
a.) C(x) = 10x + 8,000
Step-by-step explanation:
The fixed cost does not change regardless of the variable. Therefore, it should be attached to no variable. However, the variable cost does depend on the number of alarms and thus should be attached to the variable.
This makes the algebraic expression:
C(x) = 10x + 8,000
Your graph should look very similar to this. Keep in mind that our axis are slightly different. You can plot specific points on your graph by plugging random "x" values into your algebraic expression and finding the subsequent "y" values.
