Suppose the income elasticity of demand for food is 0.5 and the price elasticity of demand is -1.0. Suppose a hypothetical group of people spend $10,000 a year on food, the price of food is $2, and that their total income is $25,000. a. If a sales tax on food caused the price of food to increase to $2.50, what would happen to their consumption of food? b. Suppose they will get a tax rebate of $2500 to ease the effect of the sales tax. What would the consumption of food be now? c. Are they better or worse off when given a rebate equal to the sales tax payments? Explain.
