Trade usually benefits all the nations involved. We can use an extreme example, Chinese-American trade. America has a huge trade deficit with China, but still the whole country benefits from it. America lost some manufacturing jobs, but they have been replaced by higher paying service related jobs (currently service related jobs account for more than 70% of the total jobs in America).
And more important, American citizens are able to buy very good and cheap products from China and other places. Imagine if we had to pay for only domestic products, we would spend a much larger portion of our income in them.
Answer:
(a) Linear model
Subject to:
(b) Standard form:
Subject to:
Explanation:
Given
Solving (a): Formulate a linear programming model
From the question, we understand that:
A has a profit of $9 while B has $7
So, the linear model is:
Subject to:
Where:
Solving (b): The model in standard form:
To do this, we introduce surplus and slack variable "s"
For 
inequalities, we add surplus (add s)
Otherwise, we remove slack (minus s)
So, the standard form is:
So, the linear model is:
Subject to:

Answer:
The correct answer is Worker productivity
Explanation:
The productivity of work is the efficiency of the productive activity of men expressed by the correlation between labor expenditure (at the level of society, of a branch, of a company or of a single worker) and the amount of material goods produced (established in money or in kind) in a unit of time. It is determined by the amount of time invested in developing the production unit or by the amount of production manufactured in the time unit. The level of labor productivity is a very important index of the progressive nature of a mode of production of a given social regime. Every new social regime, Lenin said, beats the one that precedes it by achieving greater labor productivity. Raising labor productivity means saving live work and social work, that is, reducing the socially necessary time to produce the unit of merchandise, reducing its value. The proportion of living labor decreases while the proportion of past (materialized) labor increases relatively and in such a way that the overall sum of work locked up in merchandise is reduced. This law manifests the decisive meaning of the progress of the technique for the growth of labor productivity.
