If 14 acres can be treated per tank, how many pints of pesticide should be used to apply volume of 1.5 pints per acre?

To determine the correct amount of pesticide to use, you can start by calculating the total number of pints needed for the entire area to be treated. Since the application rate is 1.5 pints per acre, you can multiply this rate by the total number of acres being treated.

In this case, if you treat 14 acres and apply 1.5 pints of pesticide per acre, the calculation would be:

Total pints needed = Acres treated × Pints per acre

Total pints needed = 14 acres × 1.5 pints/acre = 21 pints.

Thus, the correct answer is indeed 21 pints. This formulation clearly shows how the total pesticide requirement is directly related to both the acreage being treated and the application rate, ensuring that the right amount of pesticide is applied for effective pest management.
