Following the increase in price of a 250g bag of coffee from £2.35 to £2.65 in a local supermarket, weekly sales of tea increase from 8.5 kg to 11.5 kg. From this we can conclude that: a) The price elasticity of demand for tea is -2.76, so that consumer’ demand for tea is highly elastic. b) The income elasticity of demand among consumers is 10, confirming that tea, but not coffee, is a luxury good. c) The cross-price elasticity of demand is 2.5, confirming that tea is a substitute for coffee. d) The price elasticity of demand for coffee is -0.4, so that the demand for coffee is price inelastic
