25) Which statement is TRUE? Elasticity of demand attempts to measure how fast quantity demanded increases when price increases. The elasticity of demand is always the same as the elasticity of supply. If the elasticity of demand is –4, then economists know that the price is increasing at a faster rate than quantity demanded. The price elasticity of demand is always a negative number, but economists generally ignore the negative sign.
