If atrazine should be applied at 2 lbs per acre, how many gallons of Aatrex should you purchase to treat 45 acres?

15 gallons
22.5 gallons
30 gallons
10 gallons

The correct answer is: 22.5 gallons

To determine how many gallons of Aatrex you need to purchase to treat 45 acres with an application rate of 2 lbs per acre, it’s essential to first calculate the total amount of atrazine required for the entire area. Start by finding the total weight of atrazine needed: - Multiply the application rate (2 lbs per acre) by the number of acres (45 acres). - This calculation gives you a total requirement of 90 lbs of atrazine (2 lbs/acre × 45 acres = 90 lbs). Next, it's critical to know the concentration of atrazine in Aatrex, which typically comes in a formulated liquid product. Assume Aatrex has a concentration, for example, of 4 lbs of atrazine per gallon. To find the total gallons required: - Divide the total atrazine needed (90 lbs) by the concentration (4 lbs/gallon). - This will give you 22.5 gallons of Aatrex (90 lbs ÷ 4 lbs/gallon = 22.5 gallons). Therefore, the correct answer is 22.5 gallons, as it accurately reflects the amount of the product required to meet the specified application rate over the given area.
