It takes 36 pounds of seed to completely plant a 5-acre field.

How many acres can be planted per pound of seed?

To find the number of acres that can be planted per pound of seed, we need to divide the total number of acres by the total amount of seed.

Number of acres per pound of seed = 5 acres / 36 pounds = 0.1388 acres per pound of seed

Therefore, approximately 0.1388 acres can be planted per pound of seed.
