Question

A job order requires you to use a miter saw to cut 38 pieces of rough stock. The pieces have to be 5 1/4" long, the width of the blade is 1/16", the boards measure 10 feet long and the operator gets paid .25 for each cut piece. How many boards will you need?

Answer 1

19.95 ≅ 20 boards will be required.

Explanation:

The pieces have to be
`5 + (1)/(4)` =
`(21)/(4)` feet long.

A total number of 38 pieces are needed to cut.

In order to make 38 pieces total required length is
`38 *(21)/(4)` =
`(19times21)/(2)` = 199.5

1 board is 10 feet long, hence total requirement of board is
`(199.5)/(10)` = 19.95
