6. Elasticity and total revenue The following graph illustrates the weekly demand curve for motorized scooters in Moline. Use the green rectangle (triangle symbols) to compute total revenue at various prices along the demand curve. Note: You will not be graded on any changes made to this graph. On the following graph, use the green point (triangle symbol) to plot the weekly total revenue when the market price is $40,$60,$80,$100,$120, $140, and $160 per scooter. According to the midpoint methed, the price elasticity of demand between points A and B is approximately Suppose the price of scooters is currently 480 per scooter, shown as point A on the intial graph. Because the demand between points A and B is , a $20-per-scooter decrease in price wis lead to. in total revenue per week. In general, in order for a price decrease to cause a decrease in total revenve, demand must be
