A pesticide label calls for a broadcast application of 2.5 pints per acre. Your sprayer holds 450 gallons and is calibrated to apply 15 gallons of spray mixture per acre. How much product is needed for each fill?

• A. 30 pints
• B. 37.5 pints
• C. 60 pints
• D. 75 pints

Answer: (D)

The amount of product you need scales with area treated. The label calls for 2.5 pints per acre, and one full tank will cover a certain number of acres based on the spray rate per acre.

First, determine how many acres are treated per fill: 450 gallons in the tank divided by 15 gallons per acre equals 30 acres per fill.

Then multiply the area per fill by the product rate per acre: 30 acres × 2.5 pints per acre = 75 pints.

So, you need 75 pints of product for each fill.
