As we produce more of one good, economists think that we must give up increasing amounts of another good. For example if car production is increased from 200 to 400 units, the sacrifice (opportunity cost) in terms of the other good will be less than when car production is increased from 400 to 600 units. Why wouldn't opportunity costs stay the same? In other words, shouldn't an additional 200 cars cost the same regardless of whether car production increases from 200 to 400, or 400 to 600?

its simple as this, microeconomics is the study of economics at an individual, group or company level, macroeconomics on the other hand, is the study of a national economy as a whole.

answer; /// the above statement is (true); good luck

a recipe serves 8 people, and calls for 5 lbs of apples and 2 cups of flour. you want to prepare it for 24 people. divide 24 by 8 to get 3, and then multiply your ingredients by 3.

so for 24 people, you'll need 15 lbs of apples, and 6 cups of flour.
