- Define gallons: Let's call the amount of solution to be added ＂＂ gallons.
- Calculate acetone in % solution: The amount of acetone in the gallons of solution is gallons.
- Calculate acetone in gallons: The amount of acetone in the gallons of solution is .
- Find total solution amount: The total amount of solution after adding ＂＂ gallons will be gallons.
- Calculate total acetone in new solution: The total amount of acetone in the new solution should be of gallons, which is $(\(100\) + x) \times \(0\).\(10\).
- Set up equation: Now we set up the equation: \(14 + (x \times 0.09) = (100 + x) \times 0.10\).
- Distribute \(0\).\(10\): Distribute the \(0.10\) on the right side of the equation: \(14 + (x \times 0.09) = 10 + (x \times 0.10)\).
- Subtract \(10\): Subtract \(10\) from both sides: \(14 - 10 + (x \times 0.09) = (x \times 0.10)\).
- Simplify left side: Simplify the left side: \(4 + (x \times 0.09) = (x \times 0.10)\).
- Subtract \(0.09x\): Subtract \((x \times 0.09)\) from both sides: \(4 = (x \times 0.10) - (x \times 0.09)\).
- Combine like terms: Combine like terms: \(4 = x \times (0.10 - 0.09)\).
- Simplify right side: Simplify the right side: \(4 = x \times 0.01\).
- Divide by \(0\).\(01\): Divide both sides by \(0.01\) to solve for \(x\): \(x = \frac{4}{0.01}\).
- Calculate x: Calculate \(x\): \(x = 400\).
