To find the total cost of having a window fixed, we need to consider both the fixed cost and the variable cost based on labor hours. The fixed cost is $175, which is the base charge for the service. The variable cost is determined by the number of hours of labor, which is $30 per hour. Therefore, if 'h' represents the number of hours of labor, the total cost can be expressed as the sum of the fixed cost and the variable cost: Total Cost = Fixed Cost + (Cost per Hour * Number of Hours) = 175 + 30h. This expression accurately represents the total cost based on the given information.
