Lisa is considering a wireless order-taking system, and she has asked you to do a cost analysis of acquiring it. Consider the following information in your analysis:

• The acquisition cost is $35,000 paid at the time of installation.
• It reduces the wait staff by one person: Figure $10 per hour, or 2020 hours per year + 18% benefits.
• Money costs are 7%
• The system may become obsolete in three years.

To conduct a cost analysis of acquiring the wireless order-taking system for Lisa, we need to consider several factors. Here's a breakdown of the different costs involved and how to calculate them:

1. Acquisition cost: The initial cost of acquiring the system is $35,000, which is paid at the time of installation.

2. Labor cost savings: The system reduces the need for one wait staff person. To calculate the labor cost savings, we need to consider their hourly wage, number of hours worked per year, and benefits.
- Assuming the wait staff person earns $10 per hour, their annual wage would be $10 x 2020 hours = $20,200.
- To account for benefits, we add an 18% markup to the annual wage: $20,200 x 0.18 = $3,636.
- Therefore, the labor cost savings per year would be $20,200 + $3,636 = $23,836.

3. Money costs: Money costs include the interest or opportunity cost associated with acquiring the system. Here, the money costs are 7%. To calculate the yearly money cost, we multiply the acquisition cost by the money cost rate:
- Yearly money cost = $35,000 x 0.07 = $2,450.

4. Obsolescence cost: As mentioned, the system may become obsolete in three years. This cost represents the potential loss of value or need to upgrade or replace the system. However, we need more information to determine the specific value for this cost, such as the estimated replacement cost or the potential decrease in efficiency if the system becomes obsolete.

To summarize the cost analysis:
- Acquisition cost: $35,000
- Labor cost savings: $23,836 per year
- Money costs: $2,450 per year
- Obsolescence cost: Requires more information.

Please note that the obsolescence cost is left open-ended as it depends on additional factors specific to the system and the business's needs. Further evaluation is necessary to determine this cost accurately.
