Answer:

The real GDP will rise by $203.70 billion

Explanation:

Marginal propensity to consume(MPC) = 0.73

Multiplier =  1 / 1 - MPC

Multiplier =  1 / 1 - 0.73

Multiplier = 1 / 0.27

Multiplier = 3.703704

Change in real GDP = Change in autonomous spending * autonomous spending multiplier

Change in real GDP = 55,000,000,000 * 3.703704

Change in real GDP = 203,703,720,000

The real GDP will rise by $203.70 billion
