8 post. I cans draw a picture

You are right.

To understand the problem and find the solution, let's break it down step by step.

1. The farmer builds a straight fence that is 49 ft long.
2. The farmer puts a post every 7 ft along the fence.
3. A post is placed at the beginning and end of the fence.

To show the relationships in the problem, we can represent the fence as a line and mark the placement of each post. Let's imagine the fence as a straight line and place the posts every 7 ft.

7ft 14ft 49ft
|-----|-----|-----|-----|-----|-----|-----|

In the above diagram, we can see that there are 7 sections of 7 ft each, with a post placed at the end of each section. Since the fence is 49 ft long, there will be a total of 7 posts - one at the beginning, one at the end, and 5 in between.

Therefore, the farmer will need 8 posts in total (including the one at the beginning and the one at the end) to build the fence.
