If the directions call for 2 pints of pesticide per 100 gallons, how much pesticide is needed for 12 gallons of spray?

To determine how much pesticide is needed for 12 gallons of spray, we need to first establish the relationship between the amount of pesticide required and the volume of spray being prepared. The directions indicate that 2 pints of pesticide is needed for every 100 gallons of spray.

First, convert the quantity of pesticide from pints to ounces, as it's often easier to work with smaller, consistent units. There are 16 ounces in 1 pint, so 2 pints is equal to:

2 pints × 16 ounces/pint = 32 ounces.

This means that for 100 gallons of spray, 32 ounces of pesticide is required. Next, we can calculate how much pesticide is required for just 12 gallons.

Set up a proportion to find out how many ounces are needed for 12 gallons.

If 100 gallons requires 32 ounces, then for 12 gallons, the required amount of pesticide (x) can be calculated as follows:

x ounces / 12 gallons = 32 ounces / 100 gallons.

Cross-multiply to solve for x:

100 * x = 12 * 32, 100x = 384, x = 384 / 100, x = 3.84 ounces.
