Answer: There is change of $0.9 billion in government expenditures.
Step-by-step explanation:
Since we know that
Marginal propensity to consume tells that the rate at which there is change in consumption due to change in income.
According to our situation, MPC is the change in amount of gross domestic product due to change in government expenditure.
So, it becomes,

Hence, there is change of $0.9 billion in government expenditures.

Answer:
(b) 15.32
Step-by-step explanation:
You can use your triangle sense to answer this.
The side x will always be shorter than the hypotenuse, 20. This eliminates the last two choices.
If the angle is 45°, then the sides are equal at about 0.707 times the length of the hypotenuse. That would make them 0.707×20 = 14.14. Since the angle is greater than 45°, the opposite side will be greater than 14.14. Only one answer choice fits between 14 and 20: the second choice -- 15.32.

The mnemonic SOH CAH TOA reminds you of the relation ...
Sin = Opposite/Hypotenuse
sin(50°) = x/20
x = 20×sin(50°) . . . . multiply by 20 to find x
x ≈ 15.32 . . . . . . . . . use your calculator to evaluate
