If 3 pints of emulsifiable concentrate are recommended per 100 gallons, how much should be added to a 300-gallon tank?

To determine how much emulsifiable concentrate should be added to a 300-gallon tank when 3 pints are recommended per 100 gallons, you start by calculating how many times 100 gallons fits into 300 gallons.

300 gallons divided by 100 gallons equals 3. This means you need to apply the recommended amount of 3 pints for each of those 100-gallon increments. Since you've established that you have three increments of 100 gallons in 300 gallons, you multiply the recommended amount (3 pints) by the number of increments (3):

3 pints x 3 = 9 pints.

Therefore, the correct amount to add to a 300-gallon tank is 9 pints. This ensures that the application rate remains consistent with the recommendation aimed at achieving effective pest control while minimizing the risk of over-application. The calculation method demystifies the reasoning behind the correct answer, allowing for a clear understanding of how to scale proportions for different tank sizes.
