Work Step by Step

Set up an equation. I will use x for the number of downloads. The earning was 9 cents per song, so in dollars it is 0.09x. Since he uses 5$ you need to subtract 5. He made 365, so the equation looks like 0.09x-5=365. Adding 5 to both sides to isolate x, you get 0.09x=370. Dividing by 0.09 to solve for x yields x=4111.11. Rounding gives 4111 downloads.
