My question is: 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? Your thoughts:
There are 900 - 42 = 858 feet of path to line. There are poles every 6 feet, so the company needs 858 / 6 = 143 poles. The poles have to go on both sides of the path, so there will be 143 * 2 = 286 fence poles along the whole path. The final answer: 286.
