Answer:

the decrease in price of used cars from $5000 to $3000 will lead to a rise in the demand of used cars by 60%

Explanation:

Mid-point method

The midpoint formula for calculating elasticity calculates change in quantity demanded and divides it by the change in the the price

The original formula is

(Q2-Q1) / (Q2-Q1)/2   / (P2-P1)  / (P2-P1/2)

Q2 is new Quantity

Q1 is old quantity

P2 is new price

P1 is old price

Since we already have the Price elasticity of demand as -1.2

the formula changes to

Percentage Change in QUantity = Price Elasticity of demand x ( (P2-P1)  / (P2-P1/2)

= -1.2 x (P2-P1)  / (P2-P1/2)

= -1.2 x (3,000-5000)  / (5000-3000/2)

-1.2 x (-2000/4000) x 100

= 60%

Therefore, the decrease in price of used cars from $5000 to $3000 will lead to a rise in the demand of used cars by 60%

Two events occur simultaneously in the market for automobiles: (1) an improvement in assembly line 'technology' and (2) the econ
kozerog [31]

Answer:

Option (d) is correct.

Explanation:

If there is an improvement in the technology then as a result the producers will be able to produce more quantity of automobiles with the same level of resources. This will increase the supply of automobiles and shift the supply curve rightwards.

At the same time, the economy is experiencing a recession. This will reduce the income of the consumers and hence, the demand for automobiles also decreases. This will lead to shift the demand curve leftwards.

As a result of these shifts in the demand and supply curve, the equilibrium price will fall and the impact on equilibrium quantity is indeterminate because it will be dependent upon the magnitude of the shift of demand and supply curve.

An investor must decide between putting $2,000 into a regular retirement plan or putting $1,440 into a Roth retirement plan. If
Novosadov [1.4K]

Answer:

They both produced the same cash amount

Explanation:

The regular retirement would have its deducted after withdrawal from the plan while Roth retirement plan's tax would have been deducted prior to investing funds in the plan

The future value of the $2000 is computed thus:

FV=PV*(1+r)^n

PV is the amount saved in the plan which is $2000

r is the growth rate of the funds in the plan which is 12%

n is the number of years the amount would be left in the plan

FV=$2000*(1+12%)^20=$ 19,292.59  

After tax amount=$ 19,292.59*(1-28%)=$ 13,890.66  

The future value of the $1,440 is computed thus:

FV=$1,440*(1+12%)^20=$ 13,890.66  

The Roth plan has not tax implication thereafter as tax was paid before savings.
