How many gallons of surfactant would you add to an 800-gallon tank at a use rate of 1/4%?

Explanation:
Use rate as a percentage of the tank volume. To find the amount to add, convert the percentage to a decimal and multiply by the total volume. 1/4% equals 0.0025. Multiply 800 gallons by 0.0025 to get 2 gallons. So you would add 2 gallons of surfactant. (Alternatively, 800 × (1/4) ÷ 100 = 2.) The key is converting the percent to a decimal before multiplying by the tank volume.
