Let's solve this step-by-step.
### Step 1: Understand the problem
We are given that 22 pounds of seed are needed to completely plant a 4-acre field. We need to determine how many pounds of seed are needed per acre.
### Step 2: Define the known values
- Total pounds of seed: 22 pounds
- Total acres: 4 acres
### Step 3: Set up the calculation
We need to find the number of pounds of seed per acre. We can do this by dividing the total pounds of seed by the total number of acres.
### Step 4: Perform the calculation
[tex]\[ \text{Pounds per acre} = \frac{\text{Total pounds of seed}}{\text{Total acres}} \][/tex]
[tex]\[ \text{Pounds per acre} = \frac{22 \text{ pounds}}{4 \text{ acres}} \][/tex]
[tex]\[ \text{Pounds per acre} = 5.5 \text{ pounds per acre} \][/tex]
### Step 5: Round the result (if necessary)
The result is already in a format that doesn't require additional rounding, but for classroom precision, we would round to the nearest hundredth if needed.
So, the number of pounds of seed needed per acre is:
[tex]\[ \boxed{5.5 \text{ pounds per acre}} \][/tex]
