What was the dosage of Sevin used per acre when 600 gallons containing 3 gallons of Sevin 4F were sprayed over 12 acres?

To determine the dosage of Sevin used per acre, we start by understanding the total amount of Sevin applied to the area. In this scenario, 3 gallons of Sevin 4F were used in a total of 600 gallons of solution sprayed over 12 acres.

First, we need to calculate the dosage of Sevin per acre. Since 3 gallons of Sevin were used for 12 acres, we divide the total amount of Sevin by the number of acres to find the amount of Sevin applied per acre.

Calculating this, we have:

3 gallons of Sevin ÷ 12 acres = 0.25 gallons of Sevin per acre.

Expressing 0.25 gallons as a fraction, we can see that it is equivalent to 1/4 gallon. This means that for every acre, 1/4 gallon of Sevin was used.

This reasoning confirms that the dosage of Sevin applied per acre is indeed 1/4 gallon, supporting the correct answer choice.
