If an aircraft treats 14 acres per tank, how many pints of pesticide should be put into the spray tank at 1.5 pints per acre?

To determine the amount of pesticide needed for an aircraft treating 14 acres at a rate of 1.5 pints per acre, you multiply the number of acres by the amount of pesticide required per acre.

First, calculate the total amount of pesticide:

14 acres x 1.5 pints per acre = 21 pints.

This calculation shows that for 14 acres treated at the specified rate, you would need 21 pints of pesticide in the spray tank. Thus, the correct answer is that 21 pints are required. Understanding this multiplication process is vital for any aerial applicator to ensure accurate dosing and effective pest control.
