It seems that you have started to describe a problem involving the production of two goods using a limited amount of available labor. However, additional information is needed to effectively assist you. Typically, to solve such problems, we would require:

• The labor required to produce one unit of each good (apples and bananas).
• Any constraints or preferences regarding the production (e.g., how many units of each good can be produced, if there's a trade-off between them, etc.).
• The goal of the problem (e.g., maximizing total production, achieving a certain ratio of goods, etc.).

Please provide more details or the specific question you want to be answered regarding the production of apples and bananas with the given labor units.
