• A) P(butane) = 0.77 atm and P(isobutane) = 19.2 atm
• B) P(butane) = 0.80 atm and P(isobutane) = 20. atm
• C) P(butane) = 19.2 atm and P(isobutane) = 0.77 atm
• D) P(butane) = 20 atm and P(isobutane) = 0.80 atm

Definitions:

Marginal Product

The additional output generated by employing one more unit of a particular input, keeping other inputs constant.

Units of Labor

Measurements used to quantify the work input by labor forces, often referring to hours worked or number of workers.

Diminishing Returns

A principle stating that if one input in the production of a commodity is increased while all other inputs are held fixed, a point will eventually be reached at which additions of the input yield progressively smaller, or diminishing, increases in output.

Marginal Product Curve

A graphical representation that shows how the addition of one more unit of a resource to production affects the output of a product.
