A straight fence is to be constructed from posts 6 inches wide and separated by lengths of chain 5 feet long. If a certain fence begins and ends with a post, which of the following could be the length of the fence in feet? (12 inches = 1 foot).  Pick:
A) 17
B) 88
C) 266
D) 2777
E) 88
Explanation:   The fence will consist of one more post than there are chains. (e.g. P-c-P-c-P).   Therefore, a total length has to be a multiple of the length of the chain plus one post (5.5) plus one post extra.We have length = (5.5n + 0.5), where n can be any positive whole number. If n= 3, length =17   17nswer: 17) 17
