It will increase $40,000 by the services provided (consumption) but will decrease $20,000 due to the imported car (negative net exports).
b. An army battalion is deployed to the border to repel a threatened Canadian invasion. The soldiers earn wages of $10,000 and use ammunition that the government bought for $5,000. The ammunition was produced using $2,000 of imported steel and 100 hours of work, for which the workers were paid $1,000. Hint: two things are produced in this example, what is the value added for each of them?
