.
The condition says that $360 is 20% less than the original price at which Mile bought the bike somewhen earlier.


So, your equation is 


(1-0.2)*x = 360,  or   0.8x = 360,


where x is the original price for Mike.  It implies that

x = 360%2F0.8 = 450.


Answer.  The cost orice of the bike was  $450.

let his cost be x:
x - 0.20x = 360 solve on the left: 1x - 0.20x = 0.80x
0.80x = 360
x = 360/0.8 divide to get your answer

p-0.2p=360

0.8p=360
