plese help . How does an economist perform a total expenditures test? What are the three possible outcomes of a total expenditures test? What do the three results mean?​

An economist performs a total expenditures test and finds that a change in price and a change in revenue move in the opposite directions.

The possible outcome of three expenditures can price change to the direction of change in total revenue or total expenditures.

Three expenditures mean you might expect the result would be that GDP would fall by $100 billion.
