3 . Elasticity and total revenue

The following graph shows the daily demand curve for bippitybops in San Francisco.

Use the green rectangle (triangle symbols) to compute total revenue at various prices along the demand curve. You will use this information to answer the questions that follow.

Note: You will not be graded on any changes made to this graph.

Hint: Select the green rectangle after you have placed it on the graph to see its area.

On the following graph, use the green point (triangle symbol) to plot the daily total revenue when the market price is $30, $45, $60, $75, $90, $105, and $120 per bippitybop.

The price elasticity of demand between points A and B on the initial graph is approximately ( 0, 0.6, 1.67, 75.02).

Suppose the price of bippitybops is currently $120 per bippitybop, shown as point A on the initial graph. Because the price elasticity of demand between points A and B is ( elastic, inelastic, unit elastic). , a $15-per-bippitybop decrease in price will lead to ( decrease, increase, no change) in total revenue per day.

In general, in order for a price increase to cause a decrease in total revenue, demand must be ( elastic, inelastic, unit elastic).

What are the correct answers from the underlined options?
