Kyle dug a 5 foot long road in his garden. He planted a seed at the beginning, and at the end of the row. He also planted a seed every 1/4 of a fat along the row. How many seats did Kyle plant in the row?

There are a total of 21 seeds planted in the row.

At the beginning and end of the 5-foot long road, Kyle planted one seed each.
In between those two seeds, there are 4 sections (quarters) of the road. In each section, Kyle planted one seed. So, there are 4 seeds in the sections.
Therefore, the total number of seeds planted by Kyle in the row is 1 (beginning) + 4 (sections) + 1 (end) = 6 seeds.
