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:
The marginal benefit from selling the vane without restoring it is $200.
Explanation:
Marginal benefits are the extra income a company can get from selling one additional unit of production.
Zane had already spent $250 in purchasing the vane and the restoration process.
Zane has two options:
- Sell the vane as it is for $200.
- Keep restoring the vane, spend $200 more and sell the vane for $500.
If Zane decides to sell the vane as it is, his marginal benefit will be $200. That would not be enough to cover his costs, this transaction will result in a $50 loss.
If Zane decides to continue the restoration, then his marginal costs will be $200 extra, but his marginal benefit would be $500. If he chose this option he could end up earning a $50 profit.
Take 40 over a 100 as a fraction and 3000 over 1 as a fraction and multiply them. 3000 multiply by 40 is =120000 and divide that by 100 would be 1200
$1200
Answer:
ELASTIC
DECREASING PRICE
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
The demand for your parking lot spaces is elastic. if the price of parking is reduced, the demand for parking would rise
