The number of washers 3/32 inch thick that can be cut from a piece of stock 25 1/2 inches long, allowing 1/16 inch for waste for each cut is
a. 160
b. 163
c. 260
d. 272
e. 408
please answer and explain

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 
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
