For one washer you must include the waste and the width so..
(3/32)+(1/16)=5/32 or 0.15625
You have 25.5 inches of pipe so how many washers can be taken from it..
25.5/0.15625=163.2
Rounding to the lower number as it will only make .2 of the 164th washer means b is the answer

math  Damon, Sunday, April 13, 2014 at 5:33pm
number of cuts = (n1)
amount wasted = 1/16 * (n1)
amount total = (3/32) n + (1/16) n  1/16
so
25 16/32 = 5 n/32 2/32
816/32 +2/32 = 5 n/32
818 = 5 n
n = 163.6 so 163
