Consumer buys 10 units of Good A when the price of Good B is $5. When the price of Good B rises to $6 (the price of Good A remaining unchanged) the consumer buys 14 units of Good A. Part A: Using an appropriate formula, calculate this Consumer’s cross Elasticity of demand for Good A. Show your working. Part B: Is Good A, a substitute for, or a complement to, Good B? Explain your reasoning.
If the price of good A falls and the quantity demanded of good B rises, A. good B is an inferior good. B. the cross elasticity of demand is positive. C. the cross elasticity of demand is negative. D. good A is an inferior good.
