Answer:
Step-by-step explanation:
#1 Number of ways picking 2 from 6 = 6C2 = 15
#2 Arranging them in a circle (consider 1 pair AB) 
can be done 
1,5  (ABBBBB)   or (5,1)
2,4 ( AABBBB) or (4,2)
3,3 
1,1 (ABABAB)
all up = 7 ways 
#3 = product of #1 and #2 = 15x7 = 105
 
        
             
        
        
        
The original price is $254.10 or 254 rounded. 154 times .65 is 100.1. Add 100.1 to the sale price which is 154 and you'll get the original, 254.
Hope this helps :)
