<span>Diminishing marginal returns - By investing in hiring an additional worker, Michelle does not receive twice the productivity compared to when she had only 1 worker. Productivity only increased by roughly 50%. I would consider the worker to be more of an investment, and thus count as diminishing marginal returns, rather than decreasing returns to scale, which I consider to apply more to assets, such as machines for manufacturing or in the case of the scenario, an additional kiln.</span>
As long as the marginal benefits are higher than the marginal costs you are better off continuing the activity.
Consider the example of eating pizza. Each slice of pizza gives you happiness and helps fill you up (marginal benefit), but each slice also has lots of calories and fat (marginal cost). As long as you are still hungry and getting enjoyment from eating, you should keep eating. But once you reach the point where you are too full then you should stop, because the costs now outweigh the benefits.

Answer:
the total work W = 29.05 kJ
the change in total internal energy is
the total heat transferred in [kJ] is Q = 1.860 kJ
Explanation:
Given that
mass of carbon dioxide in the closed system = 1 kg
Temperature = (273+30 ) K = 303 K
Pressure
Pressure
polytropic expansion n = 1.27
Note that we are also given the following data set:
R = 188.9 J/kg.K
c_v = 655 J/kg.K
So; for a polytropic process ;
Since the system does not follow the first order of thermodynamics; To calculate the total work by using the expression:
W = 29048.62222 J
W = 29.05 kJ
Thus, the total work W = 29.05 kJ
The change in internal energy can be expressed by the formula:
Hence; the change in total internal energy is
Finally; to determine the total heat transferred in [kJ]; we go by the expression for the first order of thermodynamics which say:
Total Heat Q = ΔU + W
Q = (-27.19 + 29.05)kJ
Q = 1.860 kJ
Hence; the total heat transferred in [kJ] is Q = 1.860 kJ
