Question: Exercise 5.14: Ashley spends all of her income on gasoline and food. At first she earns $100, buys 25 gallons gasoline at $2 per gallon, and purchases 10 pounds of food at $5 per pound. Her income later rises to $200, but the price of gasoline increases to $5 per gallon, and the price of food rises to $7 per pound. Is she better or worse off? Why? Draw Ashley's budget line before and after the change in income, and identify her best choice before the change.
