A TWIN problem was solved at this forum long time ago by tutor @josmiceli under this link
https://www.algebra.com/algebra/homework/word/misc/Miscellaneous_Word_Problems.faq.question.802321.html
So, I copied that solution and changed the numbers in it, respectively.
Below is the updated solution.
There is going to be 1 more post than the number of
spaces between posts. For example, if there were 10
spaces, there would be 11 posts
-----------------------------
Let = the number of ft spaces
= the number of posts
-----------------
Note that in = ft
He will use 8 posts. ANSWER
------------------
check:
OK
