Since the musician earns 0.09 for each download, the musician earns 0.09d dollars when the song is downloaded d times.Similarly, since the musician earns 0.002 each time the song is streamed, the musician earns 0.002s dollars when the song is streamed s times. Therefore, the musician earns a total of 0.09d+0.002s dollars when the song is downloaded d times and streamed s times. Choice A is incorrect because the earnings for each download and the earnings for time streamed are interchanged in the expression. Choices B and D are incorrect because in both answer choices, the musician will lose money when a song is either downloaded or streamed. However, the musician only earns money, not loses money, when the song is downloaded or streamed.
