Y=amount of money paid. (in $)
x=number of songs download.
We have this function:
y=0.25x+9.99
Then:
if y=113.74
113.74=0.25x+9.99
0.25x=113.74-9.99
0.25x=103.75
x=103.75 / 0.25
x=415
Answer: the number of songs downloaded would be 415.
The answer will go to bill Jeff 0.75
Question-

That's 20% of 305.
You could set up the problem as a ratio.
20 x
--- = ------
100 305
100x = 6100
x = 61
