Currently, a government's budget is balanced. The marginal propensity to consume is 0.75. The government has determined that each additional$10 billion in new government debt it issues to finance a budget deficit pushes up the market interest rate by .10 percent. It has also determined that every 0.10(one-tenth)percentage change in the market interest rate generates a change in planned investment expenditures equal to $4 billion. Finally, the government knows that to close a recessionary gap and take into account the resulting change in the price level, it must generate a net rightward shift in the aggregate demand curve equal to $150 billion.

Assuming that there are no direct expenditure offsets to fiscal policy, calculate the increase in government expenditures necessary to close the recessionary gap. (Hint: How much private investment spending will each $10 billion increase in government spending crowd out?)

__billion. (Enter your response rounded to two decimal places.)
