Suppose the price of local cable TV service increased from $35.00 to $38.00 and as a result the number of cable subscribers decreased from 300,000 to 280,000. Along this portion of the demand curve, using the midpoint method, price elasticity of demand is approximatelyMultiple Choice−1.11.−0.84.−0.61.−1.17.
