SOLUTION: A quantity of bolts are to be produced from a bar of 3/4" square stock 8 1/4' in length. Allowing 1/8" for waste in cutting off each bolt, calculate number of bolts that can be mad

Question 1047576: A quantity of bolts are to be produced from a bar of 3/4" square stock 8 1/4' in length. Allowing 1/8" for waste in cutting off each bolt, calculate number of bolts that can be made.

My attempt at solution:
8 1/4' = 99"
2 5/8" - 1/8" = 2 4/8" = 2.5"
99 / 2.5 = 39.6 = 40 bolts.
Where am I correct ?

Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
If I can assume the 2.5" is the size of the bolt, you need 2 5/8 inches per bolt or 21/8 inches
You have 99 inches, or 792/8 inches.
792/8/21/8=792/21
That equals 37.71, and you have to round down, not up, because a fraction of a bolt is 0 unless it is complete.
37 bolts would be my answer.
The waste must be factored into each bolt, not subtracted out. Again, I am assuming 2.5 inch bolts and the 3/4" square stock is not relevant, only the 8 1/4'
