Word Problem: Songs Downloaded

[reader1018]

My homework question is "the standard version of a song is 2.3mb and high quality is 4.2mb. There was 1120 downloads for a total of 4077mb. How many high quality songs were downloaded?" I'm having an issue creating the formula needed to solve this word problem!

Hi reader1018,

I think we can set up a system of equations to solve this. Let's call $S$ the number of standard versions downloaded and $H$ the number of high quality versions downloaded. We are told that $2.3S+4.2H=4077$. We need a second equation though to solve for both variables. What else do we know?
