Astudent has a 2% salt water solution and a 7% salt water solution. to best imitate salt water at a local beach, he needs 1 liter of a 3.5% salt water solution. he defines x as the amount of 2% solution and writes this equation: 0.2x + 0.7(x â 1) = 0.35(1) he solves the equation and determines that x is about 1.17 liters. he interprets this as needing 1.17 liters of 2% solution to make 1 liter of 3.5% solution. what errors did the student make? check all that apply.
