What errors did the student make? Check all that apply. The percent values were written incorrectly in the equation. The amount of 7% solution should be written as 1 – x, not x – 1. The equation as written is solved incorrectly. x ≠ 1.17. x must represent the amount of the more highly concentrated solution. The interpretation is incorrect. 1 liter of 2% solution is needed to make 1.17 liters of 3.5% solution.
