∻Solution∻ ‖ a ⋮ Understanding Cross-Price Elasticity of Demand: Cross-price elasticity of demand measures the responsiveness of the quantity demanded for one good when the price of another good changes. It is calculated using the formula: $E_{xy} = \frac{\% \Delta Q_x}{\% \Delta P_y}$, where $E_{xy}$ is the cross-price elasticity of demand for good x with respect to the price of good y, $\% \Delta Q_x$ is the percentage change in quantity demanded of good x, and $\% \Delta P_y$ is the percentage change in price of good y. ‖ ‖ b ⋮ Applying the Given Information: Given that Fernanda's cross-price elasticity of demand for pawpaws with respect to the price of crackers is -2, and the price of crackers increases by 50%, we can use the formula to find the percentage change in quantity demanded for pawpaws: $E_{xy} = \frac{\% \Delta Q_x}{\% \Delta P_y} \Rightarrow -2 = \frac{\% \Delta Q_{pawpaws}}{50\%}$. ‖ ‖ c ⋮ Calculating the Percentage Change in Quantity Demanded: Solving for $\% \Delta Q_{pawpaws}$ gives us $\% \Delta Q_{pawpaws} = -2 imes 50\% = -100\%$. This means that the quantity demanded for pawpaws will decrease by 100%. ‖ ∻Answer∻ ⚹ Fernanda will buy 100% fewer pawpaws. ⚹ ∻Key Concept∻ ⚹ Cross-Price Elasticity of Demand ⚹ ∻Explanation∻ ⚹ A negative cross-price elasticity of demand indicates that the two goods are complements. In this case, an increase in the price of crackers leads to a decrease in the quantity demanded for pawpaws. ⚹◊How does the cross-price elasticity of demand between two goods impact consumer behavior when prices change in macroeconomics?⍭ Generate me a similar question◊
