For a 50-gallon tank that requires 3 pints of EC per 100 gallons, how much EC should you add?

To determine how much EC (emulsifiable concentrate) to add to a 50-gallon tank when the recommendation is to use 3 pints per 100 gallons, you'll first need to set up a proportion based on the given rates.

Given that the application rate is 3 pints for every 100 gallons, the amount of EC required can be calculated for the 50-gallon tank as follows:

1. Set up the ratio of EC to gallons, which is 3 pints per 100 gallons.

2. For 50 gallons, you can use a direct proportion:

[

\text{Amount of EC} = \frac{3 \text{ pints}}{100 \text{ gallons}} \times 50 \text{ gallons}

]

3. Simplifying the equation:

[

\text{Amount of EC} = \frac{3 \times 50}{100} = \frac{150}{100} = 1.5 \text{ pints}

]

Adding 1.5 pints of EC to the 50-gallon tank ensures that you are applying the correct concentration specified in the recommendation. This calculation effectively scales the amount of EC
