When preparing a 3% foam solution, how many gallons of water are required for every 3 gallons of foam concentrate?

To prepare a 3% foam solution, you need to understand the concentration of the foam concentrate in relation to the total volume of the solution. A 3% solution means that 3% of the total mixture is foam concentrate, while the remaining 97% is water.

When you have 3 gallons of foam concentrate, you need to determine the total volume of the solution that will provide a 3% concentration. Using the formula for concentration:

[ \text{Percentage of foam concentrate} = \frac{\text{Volume of foam concentrate}}{\text{Total volume}} \times 100 ]

In this case, if you have 3 gallons of foam concentrate and this represents 3% of the total volume, you can set up the calculation as follows:

Let ( x ) be the total volume of the solution. According to the formula, we can rearrange it to:

[ 3 = 0.03 \times x ]

To solve for ( x ):

[ x = \frac{3}{0.03} ] [ x = 100 \text{ gallons} ]

Since the total solution is 100 gallons and you already have 3 gallons of foam concentrate, the amount of water
