If a tank holds 30 gallons and is to be filled with herbicide for an application rate of 3 gallons per acre, how much can the tank treat?

To determine how much area the tank can treat, you need to divide the total volume of the tank by the application rate per acre. The tank can hold 30 gallons of herbicide, and the application rate is 3 gallons per acre.

When you perform the calculation:

30 gallons (total tank capacity) ÷ 3 gallons per acre (application rate) = 10 acres

This means the tank can effectively treat up to 10 acres of land before running out of herbicide. Therefore, the answer that represents the correct area that can be treated is based on this calculation, leading to the conclusion that the appropriate choice is related to the 10-acre treatment capacity.
