A 10,500 square foot lawn is sprayed with an insecticide at the rate of 1 1/2 fluid ounces per 1,000 square feet. How much pesticide is needed for the entire lawn?

To determine the amount of insecticide required for a 10,500 square foot lawn at the application rate of 1 1/2 fluid ounces per 1,000 square feet, it's important to first calculate how many units of 1,000 square feet are present in the total area.

Start by dividing the total area of the lawn by the area that corresponds to the insecticide application rate:

10,500 square feet ÷ 1,000 square feet = 10.5

This means there are 10.5 units of 1,000 square feet in the 10,500 square foot lawn. Next, multiply that by the application rate of 1 1/2 fluid ounces per 1,000 square feet:

10.5 units × 1.5 fluid ounces = 15.75 fluid ounces

Now, to convert fluid ounces into a pint, it is important to know that 1 pint is equivalent to 16 fluid ounces. Since 15.75 fluid ounces is slightly less than 1 pint, the correct amount of pesticide needed for the lawn is just under 1 pint.

Thus, selecting 1 pint as the correct answer encompasses the entire amount needed plus a small margin for accurate
