If 2 pints of emulsifiable concentrate are recommended per 100 gallons, how many teaspoons should be added for 1 gallon?

To determine the correct answer, we first need to understand the conversion from pints to gallons and then from gallons to teaspoons.

In this case, the recommendation is for 2 pints of emulsifiable concentrate per 100 gallons of water. Since there are 8 pints in a gallon, 2 pints equal 1/4 of a gallon (2 pints ÷ 8 pints/gallon = 0.25 gallons). Therefore, the rate translates to 1/4 of a gallon of concentrate for every 100 gallons of water.

Next, we need to find out how much concentrate is needed for just 1 gallon of water. Since 1 gallon of water is 1/100th of 100 gallons, we take 1/4 of a gallon and also divide it by 100, which gives us:

(1/4 gallon) ÷ 100 = 1/400 gallons of concentrate needed for 1 gallon of water.

To convert gallons to teaspoons, we can use the fact that there are 256 teaspoons in a gallon. Now, we can compute:

(1/400 gallons) × 256 teaspoons/gallon = 0.64 teaspoons.
