How much pesticide formulation is needed for a 10,500 square-foot lawn if sprayed at 1.5 fluid ounces per 1,000 square feet?

To determine the amount of pesticide formulation required for a 10,500 square-foot lawn at a rate of 1.5 fluid ounces per 1,000 square feet, first calculate the total number of 1,000 square feet in 10,500 square feet. This can be done by dividing the total area by 1,000, resulting in 10.5.

Next, multiply the rate of application (1.5 fluid ounces) by the number of 1,000 square feet (10.5):

1.5 fluid ounces × 10.5 = 15.75 fluid ounces.

Now convert fluid ounces to pints, knowing that 1 pint is equal to 16 fluid ounces.

To convert 15.75 fluid ounces into pints, divide by 16:

15.75 fluid ounces ÷ 16 fluid ounces per pint = 0.984375 pints.

This amount rounds up to approximately 1 pint, which corresponds to the option that indicates you need 1 pint of pesticide formulation for the treatment of a 10,500 square-foot lawn. Thus, the correct answer is considered accurately calculated based on the application rate and the area to be treated.
