11	Price rises from 20 to 22 and quantity demanded falls from 500 to 450. The price elasticity of demand is A　minus 2.0, elastic B　minus 10, perfectly elastic C　minus 1.0, unit elastic D　minus 0.5, inelastic	Answer: C — Quantity falls 10% while price rises 10%, so PED = -10 / 10 = -1.0.
12	If demand for a product is price elastic, a fall in price will A　shift the demand curve right B　raise total revenue C　lower total revenue D　leave total revenue unchanged	Answer: B — With elastic demand the percentage rise in quantity exceeds the percentage fall in price.
