A college raises its annual tuition from $23,000 to $24,000, and its student enrollment falls from 4,877 to 4,705. Compute the price elasticity of demand. Is demand for the college elastic or inelastic? As the price of good X rises from $10 to $12, the quantity demanded of good Y rises from 100 units to 114 units. Are X and Y substitutes or complements? What is the cross elasticity of demand? The quantity demanded of good X rises from 130 to 145 units as income rises from $2,000 to $2,500 a month.
