Final answer:
To determine the amount of seed required per acre, divide the total quantity of seed used by the total acreage. For an 18-pound seed requirement over a 3-acre field, it equates to 6 pounds of seed per acre.
Step-by-step explanation:
To find the amount of seed needed per acre, we simply divide the total amount of seed by the total number of acres. In this case, the student has a 3-acre field and uses 18 pounds of seed to plant the entire field.
- Total seed needed: 18 pounds.
- Total field area: 3 acres.
- Amount of seed needed per acre = Total seed needed ÷ Total field area.
- Amount of seed needed per acre = 18 pounds ÷ 3 acres.
- Amount of seed needed per acre = 6 pounds per acre.
Hence, the amount of seed needed to plant one acre of the field is 6 pounds.
