Answer:
$5 billion
Explanation:
Calculation of how much would government spending have to rise
The MPC will be :0.8
First step
Using multiplier =1/1-0.8
=1/0.2
=5
Second step is to calculate the amount of the rise in government spending
=25/5
=$5 billion
Therefore the amount that the government spending would have to rise to shift the aggregate demand curve rightward by $25 billion will be $5 billion
