A farmer plans to build a fence next to a stretch of driveway. Each fence post will be one foot wide and there will be three feet of space between posts. If the driveway is 65 feet long and the fence will be on just one side of the driveway, then how many posts will the farmer need to complete the fence?

A) 16

B) 17

C) 18

D) 19

E) 20

Let's visualise a fence: Each fence post and the space to its right will account for a total of 1 + 3 = 4 feet. So to cover 64 feet, we will need 64/4 = 16 posts. The last one foot will be covered by one more fence post so in all we will need 17 fence posts

Answer (B)
