If the directions call for two pints of a pesticide per 100 gallons of spray mixture, how much would you use in 12 gallons of spray?

To determine how much pesticide to use in 12 gallons of spray, it is essential to start with the given rate, which is two pints per 100 gallons of spray mixture.

First, calculate the amount needed for 1 gallon of spray mixture. Since there are 2 pints in 100 gallons, the amount of pesticide per gallon is:

[

\frac{2 \text{ pints}}{100 \text{ gallons}} = 0.02 \text{ pints per gallon}

]

Next, multiply this rate by the 12 gallons of spray mixture:

[

0.02 \text{ pints/gallon} \times 12 \text{ gallons} = 0.24 \text{ pints}

]

Now, convert 0.24 pints into ounces, knowing there are 16 ounces in a pint:

[

0.24 \text{ pints} \times 16 \text{ ounces/pint} = 3.84 \text{ ounces}

]

Rounding this to the nearest whole number, we see that approximately 4 ounces are needed for 12 gallons of spray mixture. This leads to the conclusion that using 4 ounces will provide the
