A company is lining a 900-foot path with a fence. Every 6 feet, a fence pole is placed. The entire path is lined with a fence except for a 42-foot bridge. How many fence poles will be placed along the whole path on both sides?
assistant
How many feet of path are there? ** There are 900 - 42 = <<900-42=858>>858 feet of path to line.
How many poles are needed? ** There are poles every 6 feet, so the company needs 858 / 6 = <<858/6=143>>143 poles.
How many fence poles will be placed along the whole path on both sides? ** The poles have to go on both sides of the path, so there will be 143 * 2 = <<143*2=286>>286 fence poles along the whole path.
