B.0.002d - 0.09s
C.0.09d + 0.002s
D.0.09d - 0.02s

Answer 1

Hint: We will first find the money earned when the music is downloaded d times. Next, find the money earned when the music is streamed s times. Then, to find the total money earned, add the amount when the music is downloaded d times and when the music is streamed s times.

Complete step-by-step answer:
We are given that the musician earns 0.09 each time the song is downloaded
Also, he earns 0.002 each time the song is streamed.
The total amount of money earned when the music is downloaded can be calculated by multiplying the earnings of one download and the number of times the music is downloaded.
We are given that the music is downloaded d times and earns 0.09 each time.
Hence, total money earned if the music gets downloaded is 0.09d
Next, we will calculate the earnings when music is streamed.
The total amount of money earned when the music is streamed can be calculated by multiplying the earnings of one time when music is streamed and the number of times the music is streamed.
As given in the question, the music is streamed s times and the musician earns 0.002 when music is streamed one time.
Therefore, money earned from streaming of music is 0.002s
Now, the total money earned will be the sum of earnings from downloading and from streaming of music.
Hence, it is given by 0.09d + 0.002s
Therefore, option C is correct.


Note: Make sure to use the correct variables to multiply with the value of money earned from downloading or streaming. Also, we have to add both the earnings, that is , the earnings when the music gets downloaded and the earnings when the music is streamed, to find the total earnings.
