Nadia consumes two goods, food and clothing. The price of food is $2, the price of clothing is $5, and her income is $1,000. She always spends 40% of her income on food regardless of the price of food, clothing, or her income.
What is her price elasticity of demand for food?
What is her cross-price elasticity of demand for food with respect to clothing?
What is her income elasticity of demand for food?
Yesterday, the price of envelopes was $3 a box, and Julie was willing to buy 10 boxes. Today, the price has gone up to $3.75 a box, and Julie is now willing to buy 8 boxes. Is Julie's demand for envelopes elastic or inelastic? What is Julie's elasticity of demand?
To find Julie's elasticity of demand, we need to divide the percent change in quantity by the percent change in price.
Nadzif always spends one-fifth of his income on food. Calculate his income elasticity of demand (use the midpoint formula).

Sally currently spends $800 per year on gasoline. The price of gasoline is currently $1.00 per gallon. A contemplated excise tax on gasoline will cause the price of gasoline to rise to $1.40. What impact will the tax have on Sally's consumption of gasoline? Since the purpose of the tax is only to discourage gasoline consumption, Congress is considering a $200 income tax rebate to lessen the burden of the gasoline tax. What impact will the rebates have on Sally's consumption of gasoline? Assume that both the tax and rebate are implemented. Will Sally be worse off or better off?arrow_forward
