Suppose you own a bookstore. You believe that you can sell 40 copies per day of the latest John Grisham novel when the price is $35. You consider lowering the price to $25 and believe this will increase the quantity sold to 50 books per day. Compute the price elasticity of demand using the midpoint formula and these data. Predict what will happen to your revenue if you reduce your price.

You sell two different goods: printers and toner cartridges. The price elasticity of demand for the printers is -3.4, and you earn a revenue of RM15,000 per month from the good. You earn a revenue of RM5,000 per month from the toner cartridges. The cross price elasticity of demand for both of the goods is -2.5. If you decide to decrease the price of the printers by 5%, calculate your new total revenues for both of the goods. [Anda menjual dua barang berbeza: pencetak dan kartrij toner.

When the local pizza parlor prices pizzas at $12 each, it generally sells 7000 pizzas per month. If it lowers the price to $10, sales increase to 9000 pizzas per month. Given this information, we know that the price elasticity of demand for pizza is about 1.38, and an increase in price from $10 to $12 results in a decrease in total revenue. 0.72, and an increase in price from $10 to $12 results in an increase in total revenue. 0.72, and an increase in price from $10 to $12 results in a decrease in total revenue. 1.38, and an increase in price from $10 to $12 results in an increase in total revenue.

If Starbucks’s marketing department estimates the income elasticity of demand for its coffee to be 2.6, how will the prospect of an economic boom (expected to increase consumers’ incomes by 6 percent over the next year) impact the quantity of coffee Starbucks expects to sell?
