You calibrated your equipment to spray 50 gallons per acre. You need to spray one acre. The label calls for 3 pounds of formulation per 100 gallons of water. How much formulation should you add to the tank in order to make 50 gallons of finished spray?

You calibrated your equipment to spray 50 gallons per acre. You need to spray one acre. The label calls for 3 pounds of formulation per 100 gallons of water. How much formulation should you add to the tank in order to make 50 gallons of finished spray?

• A. 1.0 pounds
• B. 1.5 pounds
• C. 2.0 pounds
• D. 2.5 pounds

Answer: (B)

This question tests how to apply a label rate to the actual spray volume you plan to mix. The label gives 3 pounds of formulation per 100 gallons of water. To find the amount for 50 gallons of finished spray, convert the rate to a per-gallon basis and multiply by the total volume you’ll spray. Rate per gallon = 3 pounds / 100 gallons = 0.03 pounds per gallon. For 50 gallons: 0.03 pounds/gallon × 50 gallons = 1.5 pounds. So, you should add 1.5 pounds of formulation to the tank. (For context, 1.0 pound would cover about 33 gallons, 2.0 pounds about 67 gallons, etc., showing why 1.5 pounds is the correct amount for 50 gallons.)
