A straight fence is to be constructed from posts 5 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 couldnotbe the length of the fence in feet? (12 inches = 1 foot)	Choose the correct choice from the following answers
A) 17
B) 28
C) 34
D) 39
E) 50
The fence begins and ends with a post: {post = 0.5 feet}{chains = 5 feet}{post = 0.5 feet}...{chains = 5 feet}{post = 0.5 feet}   The minimum length is with 2 posts = 0.5 + 5 + 0.5=

6 feet. To increase the fence, each time we should add{post= 0.5 feet}{chains = 5 feet}, so 5.5 feet. Thus, the lengths could be:   6 feet;   5 + 5.5= 
<gadget id="calculator">5 + 5.5</gadget>
<output>10.5</output>
10.5 feet;   11.5 + 5.5= 16 feet;   17 + 5.5 = 21.5 feet;   22.5 + 5.5 = 27 feet;   28 + 5.5 = 32.5 feet;   33.5 + 5.5 = 38 feet.   ...   We skipped 34 feet.   Answer: 34.
