0.30*600p = 600p-9000
180p = 600p-9000
600p-180p = 9000
420p = 9000
p = 9000/420
p = 2.1485714

0.30 = (600p - 9000)/600p
0.30 = (600p/600p) - (9000/600p)
0.30 = 1 - 15/p
-0.7 = -15/p [Subtracted 1 from both sides]
p = (-15)/(-0.7) [Multiplied both sides by p/(-0.7)]
p = 21.43

Yeah, I made a simple error. 9000/600p is 15/p not 10.5/p. I've fixed the error and have the right answer now. Thanks for catching it!
