The following graph shows the daily demand curve for bikes in Philadelphia. 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.

Suppose the price of bikes is currentlz.f $45 per bike, shown as point B on the initial graph. Because the demand between points A and Bis v , a $15perbike increase in price will lead to V in total revenue per day. In general, in order for a price decrease to cause a decrease in total revenue, demand must be V
