You have calibrated your equipment to spray 50 gallons per acre. You need to spray 1 acre. The label calls for 3 pounds of formulation per 100 gallons of water. How many pounds of formulation should you add to the tank to make 50 gallons of finished spray?

You have calibrated your equipment to spray 50 gallons per acre. You need to spray 1 acre. The label calls for 3 pounds of formulation per 100 gallons of water. How many pounds of formulation should you add to the tank to make 50 gallons of finished spray?

• A. 1.0
• B. 1.5
• C. 2.0
• D. 2.5

Answer: (A)

To determine how many pounds of formulation to add for spraying 50 gallons, it's essential to first understand the label recommendation and then adjust it based on the volume of water you will be using. The label indicates that 3 pounds of formulation is required for every 100 gallons of water. Since you are calibrating your equipment to spray only 50 gallons, you need to calculate the formulation required for that specific volume. Using a proportionate approach, if 3 pounds are needed for 100 gallons, you can find out how much is needed for 50 gallons by recognizing that 50 gallons is half of 100 gallons. Therefore, you would want to take half of the 3 pounds: \[ \text{Required formulation} = \left(\frac{50 \text{ gallons}}{100 \text{ gallons}}\right) \times 3 \text{ pounds} = 0.5 \times 3 = 1.5 \text{ pounds} \] Therefore, when you spray 50 gallons of finished spray, you would need to add 1.5 pounds of formulation to achieve the correct mixture as per the label's recommendation. Hence, the margin of formulation calculated aligns with the ongoing requirement to
