Chain link fence is sold in 50 ft rolls. If the fence length is 395 ft and you have pre-hung gates, how many rolls are required?

• A. 6
• B. 7
• C. 8
• D. 9

Answer: (C)

When you’re buying fence in fixed-length rolls, you simply need enough total feet to reach the required distance. A single roll covers 50 ft, so to cover 395 ft you divide 395 by 50, which equals 7.9. Since you can’t buy a fraction of a roll, you must round up to the next whole roll, giving you 8 rolls. The note about pre-hung gates doesn’t change this calculation unless you were told to subtract gate widths from the total length; with the given 395 ft to cover, you still need enough rolls to reach or exceed that distance. To see why the other options don’t fit: 6 rolls cover 300 ft (not enough), 7 rolls cover 350 ft (still not enough), and 9 rolls cover 450 ft (more than needed, but you wouldn’t buy more than necessary if you don’t need extra). Eight rolls is the smallest number that meets the requirement.
