Oh shit.
Okay I fucked up in the demonstration one. Look at the worded description and then look at the math, and you can see in my first post that I inserted a 60 wehere it should have been a 30:
0.5 x 1200= 600 per 60 days
600/60= x/49

That's supposed to read:
0.5 x 1200 = 600 per 30 days
600/30 = x/49

DAGNABBIT I'm a dense one this week

Sorry guys. I have a math problem apparently!!!
