Process/Skill Questions:

What is the required dilution if the label directs a 3% solution and you must mix 3 gallons of spray? (Use the equation: % solution × total volume = amount of product; 0.03 × 3 gal = ?)
When must an applicator calculate the treatment area before spraying a roadside strip that measures 2,640 feet long and 12 feet wide? (Use the equation: Area = length × width; 2,640 ft × 12 ft = ? sq ft)
Where is nozzle output determined when a calibration test shows the sprayer delivers 45 ounces in 30 seconds? (Use the equation: GPM = ounces ÷ 128 ÷ (seconds ÷ 60); 45 ÷ 128 ÷ (30 ÷ 60) = ?)
Why is it necessary to compute spray output for high‑volume versus low‑volume applications when applying 1.5 gallons per 1,000 square feet? (Use the equation: Required volume = (application rate ÷ 1,000) × area; (1.5 ÷ 1,000) × area = ?)
How does an applicator determine the correct nozzle delivery rate when calibration requires 0.25 gallons per minute and the sprayer currently outputs 32 ounces per minute? (Use the equation: Convert ounces to gallons: ounces ÷ 128 = gallons; 32 ÷ 128 = ? compared to 0.25 GPM)
