Answer: b) lower in long-run equilibrium than in short-run equilibrium.
Explanation:
A self regulating economy will try to move to the long run Equilibrium.
From the graph attached you will notice that the Price Level at the point where the Long Run Curve intersects with the Aggregate Demand curve is lower than the point where the Short Run Supply curve intersects with the same Aggregate Supply.
This means that Prices in the long term at equilibrium will be less than prices in the short term at Equilibrium should the Economy be a self regulating type that will move towards a long term Equilibrium.
Answer:
CPI for the current year = 200
Explanation:
Given;
Contents in market basket
20X, 30Y, and 50Z
The current-year prices for goods
X = $2
Y = $6
Z = $10
The base-year prices are
X = $1
Y = $3
Z = $5
Now,
Total cost of market basket in the current year
= ∑ (Quantity × Price)
= 20 × $2 + 30 × $6 + 50 × $10
= $40 + $180 + $500
= $720
Total cost of market basket in the base year
= ∑ (Quantity × Price)
= 20 × $1 + 30 × $3 + 50 × $5
= $20 + $90 + $250
= $360
also,
CPI for the current year = 
or
CPI for the current year = 
or
CPI for the current year = 200
