#p is defined as 2p-20 for any number p. What is p, if #(#(#p))=6?  Choose the correct option
A) – 108
B) – 44
C) 10
D) 16
E) 18.25

Rationale: # p = 2 p - 20 - - - > # ( # p ) = 2 ( 2 p - 20 ) - 20 = 4 p - 60 and thus # ( 4 p - 60 ) = 2 ( 4 p - 60 ) - 20 = 8 p - 140 = 6 - - - > 8 p = 146 - - - > p = 18.25 , e is the correct answer .
Answer: E
