Final answer:
The equation representing the total cost of the home theater system is Cost = 75h + 65, where h represents the number of hours required for setup.
Step-by-step explanation:
To represent the total cost of setting up the home theater system, we can use the equation:
Cost = 75h + 65
Where:
- Cost is the total cost of the home theater system
- h is the number of hours required for the setup
In this equation, the variable h represents the number of hours required for setting up the home theater system. The fixed cost component, $65, represents the service fee. The variable component, $75, represents the cost per hour of setup.
