Based on the current level of GDP, the investment spending, and the MPC, the new level of the real GDP will be $195 million.
First find the investment multiplier as:
= 1 / (1 - MPC)
= 1 / (1 - 0.7)
= 3.333
The new level of GDP is:
= Current level of GDP + (Investment spending x Multiplier)
= 150 + (13.5 x 3.333)
= $195 million
