Use production data to connect inputs and output, calculate productivity measures, and identify diminishing marginal returns and returns to scale.
The table provided shows the short-run production function for Lowen Feline, a profit-maximizing firm that produces cat food.

Lowen Feline sells as many bags of cat food as it wants at a market price of $ 10 per bag and hires as many workers as it wants at a market wage of $ 18.
With the hiring of which worker do diminishing marginal returns begin? Explain using numbers.
State that diminishing marginal returns to labor begin with the hiring of the 3rd worker
and explain that the marginal product of the 1st worker is 5 bags, the marginal product of
the 2nd worker increases to 7 bags, and the marginal product of the 3rd worker decreases
to 6 bags.
