John’s Jelly Bean Jungle currently employs 10 workers and manufactures 100,000 pounds of jelly beans each year. The workers each earn $30,000 per year. Which of the following statements is true?

Let's analyze the statements based on the information provided:

1. **There are currently diminishing marginal returns.**
- We don't have enough information to determine whether there are diminishing marginal returns, as this depends on the relationship between the number of workers and the output produced.

2. **The average product is 10,000 pounds of jelly beans per worker.**
- The average product (AP) can be calculated by dividing the total output by the number of workers:
\[
AP = \frac{Total \,Output}{Number \,of \,Workers} = \frac{100,000 \text{ pounds}}{10 \text{ workers}} = 10,000 \text{ pounds/worker}
\]
- This statement is **true**.

3. **The average product is 100,000 pounds of jelly beans each year.**
- This statement is false, as the average product is calculated per worker, not the total output.

4. **The marginal product of the 10th worker is 9,000 pounds of jelly beans.**
- We do not have enough information to determine the marginal product of the 10th worker, so we cannot confirm this statement.

Based on the calculations, the true statement is: **The average product is 10,000 pounds of jelly beans per worker.**
