Which of the following scenarios would lead to a positive Cross-Price Elasticity of Demand (XED) and a negative Income Elasticity of Demand (YED) for Good A?

If the Price Elasticity of Demand (PED) for a particular brand of organic coffee is 0.4, how will a 10% increase in its price affect the total revenue of the seller?

A firm currently sells its product at a price of \(\$50\). Market research indicates that the price elasticity of demand (PED) for the product is \(1.5\). If the firm decides to decrease the price of the product by \(10\%\), what is the most likely outcome for the quantity demanded and the firm's total revenue?

A local electronics retailer monitors the relationship between the prices of Brand X Smartphones and the demand for Brand Y Wireless Earbuds. Currently, the price of Brand X Smartphones is \$800\), and the quantity of Brand Y Earbuds sold is 150\) units per month. When the price of Brand X Smartphones falls to \$640\), the quantity of Brand Y Earbuds sold increases to 210\) units.
