Answer:
The answer is "$110 billion".
Step-by-step explanation:
Firms increase their investment by $11 billion
mpc = 0.9
gdp = ?
To find the gdp, first we have to find expenditure multiplier;
we will find that by using the formula;
expenditure multiplier = 1/(1-0.9) = 1/0.1 = 10
Now gdp = 10 x $11 billion
= $110 billion
Thus the gdp is $110 billion.
