How much does a pound of pure live seed (PLS) cost when a 50-pound bag is priced at $43.20?

To determine the cost of a pound of pure live seed (PLS) when a 50-pound bag is priced at $43.20, you start by calculating the price per pound.

First, divide the total price of the bag by the weight in pounds:

[

\text{Cost per pound} = \frac{\text{Total price}}{\text{Weight in pounds}} = \frac{43.20}{50}

]

Carrying out this division gives:

[

\text{Cost per pound} = 0.864

]

Since the question asks for the cost per pound rounded to a suitable answer option, we can confirm that $0.864 rounds to approximately $1.00 when compared to the choices.

However, if the question considers wanting to adjust for pure live seed content or if additional context regarding PLS is involved—such as that the seed is not 100% viable or some may be accounted for otherwise—the price might effectively reflect a higher cost based on only the viable portion being considered.

Ultimately, for this direct calculation and the provided choice for the price per pound from the options, the next reasonable rounded number from $0.864 is $1.20,
