Suppоse demаnd fоr а prоduct is given аs q = -2p + 300. Answering the following questions: a) dq/dp = [a] b) We know Elasticity of Demand is given by E(p) = (-dq/dp)*p/q. To find the elasticity of demand at any price, plug in your answer from part a into the formula for elasticity of demand. Also, replace q with q = -2p + 300. This means that Elasticity of Demand would be: E(p) = [-dqdp]*p/[q1] c) Find the elasticity of demand if the price is $50 per unit. E(50) = 2*50/(-2*50+300) E(50) = [E] d) Since E(50) is [sign] 1, demand is [elasticity]. Therefore, an increase in price would [incdec] total revenue.
