What is the formula for calculating aggregate demand?

The formula for calculating aggregate demand is articulated through the equation C + I + G + (X - M), where C represents consumption, I stands for investment, G denotes government spending, X indicates exports, and M symbolizes imports.

In the context of aggregate demand, consumption, investment, and government spending collectively account for domestic demand. The term (X - M) adjusts this total by factoring in net exports, which reflect how much a country exports versus imports. When exports exceed imports (X>M), this positively contributes to aggregate demand, while a trade deficit (M>X) reduces it.

The correct option incorporates all components of aggregate demand, showcasing the interdependencies between domestic and international economic activities. Thus, the formula captures the overall economic activity represented in the aggregate demand, providing a comprehensive view of total demand within an economy.
