Final answer:
The expected maintenance costs for Stazler, Inc. include fixed costs of $64,900 per year, but the total costs cannot be calculated without the variable, operating, and administrative costs. Total costs are the sum of fixed and variable costs, as demonstrated in the barber shop example.
Step-by-step explanation:
To calculate the expected maintenance costs for Stazler, Inc., we need to consider both fixed and variable costs. The provided information mentions fixed costs, such as salaries and tools, amounting to $64,900 per year. However, the details for variable, operating, and administrative costs are not provided. Using the additional reference information, we understand that total costs are the sum of fixed plus variable costs. For instance, The Clip Joint has fixed costs of $160 per day and variable costs based on the number of barbers hired at $80 per barber each day.If we relate this to Stazler, Inc., the fixed costs are known, but to determine the total costs, we would also need to know the variable costs associated with their maintenance activities. Without this information, we cannot provide a complete answer for the expected maintenance department costs. Nevertheless, it's important to note that a business like the center mentioned should continue in business if revenues exceed variable costs, as is the case with revenues of $20,000 and variable costs of $15,000. Conversely, the business should consider shutting down if variable costs exceed revenues, such as in the scenario where variable costs are $15,000 but revenues are only $10,000.
