Question

Эластичность спроса по цене на радиоприемники равна 6.Цена спроса на них возросла на 20%.Рассчитайте изменение величины спроса.

Answer 1

Эластичность спроса по цене на радиоприемники равна 6, т. е. 100%, а возросла на 20%, значит стала 120%
6 - 100%
х -120%
х=6*120 /100
х=7,2, т. е. Эластичность спроса по цене на радиоприемники увеличилась на
7,2-6=1,2

Answer 2

Elasticity of Demand Formula

The elasticity of demand measures the responsiveness of the quantity demanded of a product to a change in its price. It is calculated using the following formula:

Elasticity of Demand = Percentage Change in Quantity Demanded / Percentage Change in Price

In this case, the elasticity of demand for radio receivers is given as 6. This means that for every 1% increase in price, the quantity demanded decreases by 6%.

Calculation of the Change in Quantity Demanded

The price of radio receivers has increased by 20%. To calculate the change in quantity demanded, we need to determine the percentage change in quantity demanded.

Let's assume the initial quantity demanded is Q1 and the initial price is P1. The new price is P2, which is 20% higher than P1. The change in quantity demanded can be calculated using the following formula:

Change in Quantity Demanded = Elasticity of Demand * Percentage Change in Price

Substituting the given values:

Change in Quantity Demanded = 6 * 20%

Calculating the change in quantity demanded:

Change in Quantity Demanded = 6 * 0.20 = 1.2

Therefore, the change in the quantity demanded of radio receivers is 1.2.

Please note that the above calculation assumes a linear demand curve and does not take into account other factors that may affect the demand for radio receivers.
