A market study of the consumer electronics industry estimated the cross elasticity of demand for smart printers to be -0.85 in response to changes in the price of proprietary ink cartridges. This implies that an 8% increase in the price of proprietary ink cartridges will cause the percentage change in demand for smart printers to be:
−9.4-9.4−9.4
−6.8-6.8−6.8
−0.11-0.11−0.11
6.86.86.8
