The table below shows part of the aggregate demand schedule for smart phones in the country of Afluentia: Quantity demanded Price P QD $900 10,000 $700 14,000 i. Plot the demand curve for smart phones in Afluentia. Assume demand is linear. Calculate the price elasticity of demand when the price increases from $700 to $900 using the midpoint method. Make your calculations explicit. ii. All else being the same, what is Afluentia's total expenditure on smart phones when the price is $700? And when the price is $900?
