Currently charges .67 for an all day ticket, and is used by an average of 513 riders a day. The bus company is not earning a profit but according to their contract with the city they can't cut the number of buses on the road. They must therefore find a way to increase revenues. The bus company is increasing the ticket price to .78. The marketing department studies indicate this price increase would reduce usage to 223 riders per day. Calculate the absolute value of price elasticity of demand for bus tickets using the simple percentage change method to determine if the bus company should increase price or decrease price to increase revenues.
Price elastic of demand is 3.4.Demand is elastic, so decreasing ticket prices will increase revenue
