To create a 3% foam solution using 20 gallons of foam concentrate, how much water is needed?

To create a 3% foam solution using 20 gallons of foam concentrate, how much water is needed?

• A. 600 gallons
• B. 6000 gallons
• C. 1500 gallons
• D. 3000 gallons

Answer: (B)

To determine how much water is needed to create a 3% foam solution using 20 gallons of foam concentrate, we first need to understand the proportion of foam concentrate to the total solution. A 3% foam solution means that 3% of the total volume will be foam concentrate, while the remaining volume will be water. Therefore, if you have 20 gallons of concentrate, this represents 3% of the total volume of solution. To find the total volume of the solution (which includes both the foam concentrate and the water), you can set up an equation: Total volume = Volume of foam concentrate / Concentration percentage In this case: Total volume = 20 gallons / 0.03 (since 3% is the same as 0.03 in decimal form) Calculating that gives: Total volume = 20 / 0.03 = 666.67 gallons This total volume represents both the foam concentrate and the water. To find out how much water is needed, subtract the amount of foam concentrate from the total volume: Water needed = Total volume - Volume of foam concentrate Water needed = 666.67 gallons - 20 gallons = 646.67 gallons However, rounding to the nearest

To determine how much water is needed to create a 3% foam solution using 20 gallons of foam concentrate, we first need to understand the proportion of foam concentrate to the total solution.

A 3% foam solution means that 3% of the total volume will be foam concentrate, while the remaining volume will be water. Therefore, if you have 20 gallons of concentrate, this represents 3% of the total volume of solution.

To find the total volume of the solution (which includes both the foam concentrate and the water), you can set up an equation:

Total volume = Volume of foam concentrate / Concentration percentage

In this case:

Total volume = 20 gallons / 0.03 (since 3% is the same as 0.03 in decimal form)

Calculating that gives:

Total volume = 20 / 0.03 = 666.67 gallons

This total volume represents both the foam concentrate and the water. To find out how much water is needed, subtract the amount of foam concentrate from the total volume:

Water needed = Total volume - Volume of foam concentrate

Water needed = 666.67 gallons - 20 gallons = 646.67 gallons

However, rounding to the nearest
