2i. Suppose the price of peanuts increased from 20 cents per pound to 30 cents per pound, and the quantity of peanuts purchased fell from 275 million pounds per month to 225 million pounds. The price elasticity of demand for peanuts is
Price elasticity of demand = Percentage change in quantity demanded/Percentage change in price = -18.18/50 = 0.36
2ii. What is the effect of the change in the peanut market for the market for peanut butter?
