If 2 pints of EC are recommended per 100 gallons, how many teaspoons would you add for 1 gallon?

1. 1 teaspoon

2. 2 teaspoons

3. 3 teaspoons

4. 4 teaspoons

The correct answer is: 2 teaspoons

To determine how many teaspoons to add per gallon when the recommendation is 2 pints of an emulsifiable concentrate (EC) per 100 gallons, it’s important to first convert units appropriately. 1 gallon is equivalent to 8 pints. Therefore, if 2 pints are required for 100 gallons, you need to find out how much is needed for just 1 gallon. To calculate this, you can set up a proportion based on the ratio given in the recommendation: - If 2 pints are used for 100 gallons, for 1 gallon: \[ \text{Pints per gallon} = \frac{2 \text{ pints}}{100 \text{ gallons}} = 0.02 \text{ pints per gallon} \] 2. Since 1 pint equals 16 fluid ounces, and there are 8 fluid ounces in a cup, that means: - The total amount in ounces for 2 pints is \(2 \text{ pints} \times 16 \text{ ounces/pint} = 32 \text{ ounces}\). 3. For 1 gallon (which is 128 ounces), the calculation of how many ounces per gallon
