I'm lookin at two questions on Economic home4 chapters 6 and 9. How is #2 "If the price elasticity of demand is 4 and the firm increases price, revenue will" increase, while #3"If the price elasticity of demand is .2 and the firm increases price, revenue will" decrease? If the frim increases the price, then wouldn't the revenue have the same effect, so they would have the same anwser?
