well, the amount used for n washers is
3/32 n + 1/16 (n-1) = 5/32 n - 1/16
since there are only n-1 waste cuts for n washers.
So, now you need to find n such that
5/32 n - 1/16 <= 25 1/2
n < 163 3/5
So, 163 washers may be cut
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
