Is this correct?

The hourly demand for music downloads is given by: Q =500 -100P where Q" is the number of songs demanded per hour and P is the price of downloading a song. Suppose that P = $3.50. The price elasticity of demand will be equal to -2.33 . (Round your answer to two decimal places.) The total revenue will be equal to $ 525 The price elasticity of demand, & = 1, when the price is equal to $ 2.50 . (Round your answer to two decimal places.) When the price is $2.50, the total revenue is equal to $ 625 The above two cases are consistent with the total revenue test since a fall in price is leading to a rise in total revenue in the presence of an elastic demand
