For a 300 gallon tank that requires 3 pints of emulsifiable concentrate per 100 gallons, how much EC should you add?

1. 6 pints

2. 9 pints

3. 12 pints

4. 15 pints

The correct answer is: 9 pints

To determine the correct amount of emulsifiable concentrate (EC) to add to a 300-gallon tank, you first need to understand the dosage specified, which is 3 pints of EC for every 100 gallons of water. Since the tank holds 300 gallons, you can calculate how many 100-gallon increments are in 300 gallons. This can be done by dividing 300 by 100, yielding 3 increments (300 ÷ 100 = 3). Next, to find the total amount of EC needed, you multiply the number of increments (3) by the required amount of EC per increment (3 pints): 3 increments × 3 pints per increment = 9 pints. Thus, for a 300-gallon tank requiring 3 pints of emulsifiable concentrate per 100 gallons, you should add a total of 9 pints of EC.
