O 0.22.
An end-of-aisle price promotion changes the price elasticity of a good from -4 to -5. Suppose the normal price is $48, which equates marginal
revenue with marginal cost at the initial elasticity of -4.
What should the promotional price be when the elasticity changes to -5? (Hint: In other words, what price will equate marginal revenue and marginal
cost?)
O $27.00
O $45.00
O $36.00
O $31.50

According to the midpoint method, the price elasticity of demand between points A and B is approximately ▼
Suppose the price of bikes is currently $30 per bike, shown as point B on the initial graph. Because the demand between points A and B is
a $15-per-bike increase in price will lead to
in total revenue per day.
In general, in order for a price decrease to cause a decrease in total revenue, demand must be
