Answer:
- 0.80
Explanation:
Price elasticity of demand describes the extent to which the quantity demanded of good X changes as result of a change in its own price.
The midpoint formula for price elasticity of demand is presented and used as follows:
Percentage change in quantity = %ΔQ = [Q2 - Q1] / [(Q2 + Q1) ÷ 2] × 100
Percentage change in quantity = %ΔP = [P2 - P1] / [(P2 + P1) ÷ 2] × 100
Midpoint price elasticity of demand = %ΔQ / %ΔP
Where:
Q2 = New quantity of good X = 150
Q1 = Initial quantity of good X = 100
P2 = New price of good X = $6
P1 = Initial price of good X = $10
Therefore,
Percentage change in quantity = %ΔQ = [150 - 100] / [(150 + 100) ÷ 2] × 100
= [50/(250 ÷ 2)] × 100
= (50/125) × 100
= 40.00%
Percentage change in quantity = %ΔP = [$6 - $10] / [($6 + $10) ÷ 2] × 100
= [-$4/($16 ÷ $2)] × 100
= (-$4/$8) × 100
= - 50.00%
Price elasticity of demand = 40% / 50% = - 0.80
The elasticity of demand of -0.80 less than 1. That indicate that the quantity demand is inelastic. That is the change in the degree of change in the quantity demanded of good X is lower than the degree of change in its price.
monetary policy. The quanity of money and interest rates are examples of monetary policy
Answer:
IRR= 20%
Explanation:
The Internal Rate of Return (IRR) tries to find the profitability of the money that remains invested during the life of a proyect. It is also known as the discount rate that makes the Net Present Value (NPV) equal to cero. When the NPV is equal to cero, then the proyect does not create or destroy value. So, if we calculate the NPV with the IRR we will find that it is equal to cero. In this case, if the cost of capital were 20% the proyect will not create or destroy value, but the problem is giving us a cost of capital that is less than 20%, then the proyect creates value. If we calculate the NPV with the rate of 16% it will be grater than zero.
The figure attached shows the IRR formula. But i calculated using Excel: first i put the cash flows of each year ( the first one is negative because it is an investment ). Then i used the formula: "=IRR(C4:C8)"
