If you need to add 3 pints of emulsifiable concentrate (EC) per 100 gallons, how much EC must go into a 300-gallon tank?

To determine how much emulsifiable concentrate (EC) is needed for a 300-gallon tank, you start by recognizing the initial prescription of 3 pints per 100 gallons. To find out the total amount needed for 300 gallons, you can scale up the calculation based on this ratio.

First, establish how many full 100-gallon segments are in 300 gallons. Since 300 gallons is three times 100 gallons, you multiply the amount of EC needed for one 100-gallon segment by 3.

Thus, if you require 3 pints for each 100 gallons, multiplying that by 3 gives you:

3 pints x 3 = 9 pints

This means you will need 9 pints of emulsifiable concentrate to adequately treat a 300-gallon tank.
