To determine how many ounces of concentrate are needed to create 300 gallons of finished spray for treating termites, you need to know the dilution rate for the concentrate that is typically used.

For many pesticide concentrates, the dilution rate might be specified as a certain number of ounces of concentrate per gallon of finished solution. The general calculation involves multiplying the number of gallons required by the ounces of concentrate needed per gallon.

If the specific dilution ratio is, for example, 0.25 ounces per gallon, you would calculate it as follows:

  1. Multiply the total gallons needed (300) by the ounces of concentrate required per gallon.

  2. In this case, it would be 300 gallons × 0.25 ounces per gallon, which equals 75 ounces.

However, if we consider the provided answer of 99 ounces, it suggests that the dilution rate is slightly higher, like 0.33 ounces per gallon or so, which would yield a larger total for the concentrate needed to prepare the mixture. This means that by using 99 ounces of concentrate, you can achieve the desired 300 gallons of the finished treatment spray.

The correct answer indicates an understanding of both the requirement for the amount of finished product you need and the concentration of the
