Answer:

increase by 400 billion dollars

Explanation:

marginal propensity to consume = mpc

tax multiplier = -mpc/1-mpc

from our question we were given mpc to be 0.8

-0.8/1-0.8

= -0.8/0.2

= -4

change in output = -4(-100)

= 400 billion dollars

for a $100 tax decrease, output will increase by $100 billion x 4

= $400 billion
