Thank you so much. That 200,000 thingy confused me so I had a hard time making my equation. Thanks for the help!

My working equations were 15/(s+c) = 5 - 15/(s-c) and 15/(2s+c) = 15/(2s-c) - 1 Whichever I use, I can't seem to get the right values of s and c. My answers are not in the choices given.

Oh yeah, I see that. Well, I guess I'm a bit confused with the less thingy. Anyway, could you please explain how you got 4&2? Thank you.

Nevermind, I got it. Thanks for all the help!
