Answer:
B) 790-700r
Explanation:
Aggregate Expenditure is the expenditure by all the sectors of economy. By Households = Consumption (C), By Firms = Investment (I), By government = Govt spending (G) & tax leakages (T), By Rest world = Next Exports (NX).
Autonomous Expenditure is the level of expenditure in economy, which doesn't depend on level of Income = Y.
AE = C + I + G + NX
[500 + 0.8 (Y-150) - 300r] + [200 - 400r] + 200 + 10
500 + 0.8Y - 120 - 300r + 200 - 400r + 210
500 - 120 + 200 + 210 - 300r - 400r + 0.8y
790 - 700r + 0.8y
As, it can be seen that the part of AE = '790 - 700r', excluding '0.8y' : is not dependent on Income Y. So, it is Autonomous Expenditure
Answer:
4.89%
Explanation:
Real rate of return = 3.37%
Inflation rate = 1.47%
The nominal rate of return is computed as shown below:
= [ (1 + real rate of return) x (1 + inflation rate) ] - 1
= [ (1 + 0.0337) x (1 + 0.0147) ] - 1
= (1.0337 * 1.0147) - 1
= 1.04889539 - 1
= 0.04889539
= 4.889539%
= 4.89% approx.

Answer:
X (the variable on the horizontal axis) will increases by 2.
Explanation:
The slope of a straight line is -3. So, m=6.
Slope of a straight line is

Y (the variable on the vertical axis) decreases by 6.
Change is y = -6
We need to find the change in (the variable on the horizontal axis).
Substitute the given values in the above formula.



Note: All options are incorrect.
Therefore, X (the variable on the horizontal axis) will increases by 2.
