Final answer:
The calculation for the cost per unit in year 5 cannot be determined with the given information because there is no provided context or formula that links the data to the cost per unit for that specific year.
Step-by-step explanation:
To determine the cost per unit in year 5 from the given information, we need additional context or a formula that relates the provided data to the cost per unit. Without this context or formula, it's impossible to accurately calculate or identify the cost per unit for year 5. The given data includes various totals for different years, technology costs, total costs with rising labor costs, the total cost of technology across years, and revenues or values for certain years. However, no clear relationship is provided between these figures and the cost per unit for a specific year. Therefore, I am unable to answer the question with the information provided.
