Answer:
The correct answer is option a. 
Explanation:
The aggregate demand in an economy comprises of consumer spending, government spending, investment expenditure, and net exports. 
An increase in any of these components will cause the aggregate demand to increase or decrease. 
So when the government spending increases the aggregate demand will increase. This increase in the aggregate demand will cause the aggregate demand curve to shift to the right. 
This rightward shift in the aggregate demand curve will cause the price level and equilibrium quantity to increase.

Answer:
Cost of land = $1,005,000
Cost of building = $4,275,000
Explanation:
The calculation of cost of the land and new building is shown below:-
Cost of land = Purchase cost + Demolition of old building + Legal fees for title investigation and purchase contract - Salvaged materials
= $960,000 + $ 60,000 + 15,000 - $30,000
= $1,005,000
Cost of building = Architects Fees + Construction costs
= $105,000 + $4,170,000
= $4,275,000
