Suppose that the demand schedule for rice for a Saudi family is as follows:
Price
Quantity Demanded
Of Rice Per Month
(income = SR 10,000)
Quantity Demanded
Of Rice Per Month
(income = SR 15,000)
SR 5 60 70
SR 4 80 95
SR 3 100 120
SR 2 120 145
SR 1 140 170
a. Calculate the income elasticity of demand of this family as their income increases from
SR 10,000 to SR15,000 if (i) the price is SR 3 and (ii) the price is SR 1.
