🔍 Key Concepts

• Foam concentrate percentage tells you what fraction of the final foam solution is concentrate • To find total foam solution, relate part concentrate to whole mixture (solution) • Use basic proportion: part / whole = percent (as a decimal)

💭 Think About

• If 6% of the total foam solution is concentrate, how do you write that as an equation using 40 gallons as the 6%? • Convert 6% to a decimal and ask: 40 gallons is 6% of what total amount? • Once you find the total foam solution, which answer choice is closest to that number?

✅ Before You Answer

• Convert 6% to a decimal before doing any math • Set up the proportion as: concentrate volume = percent × total solution volume (or rearranged to solve for total volume) • Double-check that your final total solution volume is greater than 40 gallons, since you are diluting the concentrate with water
