When applying 4 ounces per acre of an 8 WP formulation from 5-pound bags, how many bags are required to treat 100 acres?

To determine how many bags are required to treat 100 acres with 4 ounces per acre of an 8 WP formulation from 5-pound bags, we start by calculating the total amount needed for the entire area.

1. Calculate the total ounces needed for 100 acres:

If the application rate is 4 ounces per acre, for 100 acres, the total amount needed is:

[

4 \text{ ounces/acre} \times 100 \text{ acres} = 400 \text{ ounces}

]

2. Convert ounces to pounds:

Since there are 16 ounces in a pound, we convert the total ounces to pounds:

[

\frac{400 \text{ ounces}}{16 \text{ ounces/pound}} = 25 \text{ pounds}

]

3. Determine how many bags are needed:

Each bag contains 5 pounds. To find out how many bags are necessary to obtain 25 pounds:

[

\frac{25 \text{ pounds}}{5 \text{ pounds/bag}} = 5 \text{ bags}

]

Thus, the correct answer indicates that
