Hmm, I think you would take 40 and multiply it by 2 because her sister used "twice as many". Then I'm pretty sure you would take your answer from that and divide it by 2 because she used that amount of paper in "half the number of days"?
40 x 2 = 80 all together used
80 / 2 = 40 how many used each day
Is that what you were asking? If I'm wrong let me know please

Let s be standard and h be high-quality versions of the song.
To figure this out, let's make a system of equations:
2.5s + 4.5h = 5740
h = 4s
First substitute the second equation into the first for h.
2.5s + 18s =5740
Then combine like terms.
20.5s = 5740
Lastly, divide each side by 20.5 to get the number of standard downloads:
s = 280
Hope this helps!
