Price Quantity Demanded Income = Rs. 20000 Quantity Demanded Income = Rs. 24000 Rs. 18 80 DVDs 100 DVDs 20 70 90 24 55 60 28 35 40 32 24 28     Use the midpoint method to calculate your price elasticity of demand as the price of DVDs increases from Rs.24 to Rs.28 if (i) your income is Rs.20000 and (ii) your income is Rs.24000. Calculate your income elasticity of demand as your income increases from Rs. 20,000 to $24,000 if (i) the price is Rs.18 and (ii) the price is Rs.20.

Suppose the price elasticity of demand for coke is −3 and the cross-price elasticity of demand between coke and the price of Pepsi is 2.2. If the price of Pepsi decreases by 5%, what would happen to the demand for coke and what would have to happen to the price of coke to exactly offset the fall in the price of Pepsi and leave the quantity demanded of coke unchanged, respectively?

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 the current price elasticity of demand for apples is -50, what will be the change in sales (i.e., total revenue) after a 20% price increase? Please show your calculation.
