Answer:

D) Total spending will increase by $10 billion.

Step-by-step explanation:

The computation is shown below:

As we know that

Multiplier = 1 ÷ 1 -MPC

= 1 ÷ 1 - 0.75

= 1 ÷ 0.25

= 4

When there is a decrease in tax so the total spending increase is $30 billion

And, the reduction in spending because of the reduction in the government expenditure is $20 billion

So, the increase in total spending is

= $30 billion - $20 billion

= $10 billions

hence, the correct option is D.
