Answer:

The answer is: A) decrease by $50 billion.

Explanation:

An economic multiplier is an economic factor that when changed, causes changes in related economic variables. It amplifies or decreases the base value of economic variables.

In this case the economy's multiplier is two, so any change in a component of the GDP will cause twice the effect on the total GDP.

A $25 billion decrease in government x 2 = $50 billion decrease in GDP.
