Question

По цене 400 руб. было продано 250 ед. товара, а после повышения цены на 100 руб. объем продаж снизился до 200 ед. Рассчитайте дуговую эластичность спроса по цене.

Answer 1

 
коэфф = (200-250)÷(500-400) × (400+500) ÷(250+200) = -10

Answer 2

Calculation of Price Elasticity of Demand

To calculate the price elasticity of demand, we need to use the formula:

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

Given the following information:

- Initial price: 400 rubles - Initial quantity sold: 250 units - Price increase: 100 rubles - New quantity sold: 200 units

Let's calculate the percentage changes in quantity demanded and price:

Percentage Change in Quantity Demanded = ((New Quantity - Initial Quantity) / Initial Quantity) * 100

Percentage Change in Price = ((New Price - Initial Price) / Initial Price) * 100

Substituting the values into the formula:

Percentage Change in Quantity Demanded = ((200 - 250) / 250) * 100 = -20%

Percentage Change in Price = ((500 - 400) / 400) * 100 = 25%

Now, we can calculate the price elasticity of demand:

Price Elasticity of Demand = (-20% / 25%) = -0.8

The price elasticity of demand in this case is -0.8. This means that the demand for the product is inelastic, as the absolute value of the elasticity is less than 1. Inelastic demand indicates that a change in price has a proportionally smaller impact on the quantity demanded.

Please note that the calculation assumes a linear relationship between price and quantity demanded, which may not always hold in real-world scenarios.
