.5x+.8(105-x)=.6*105
x = x=70
so, (a)
Even without doing the calculation, this can be easily solved.
Since 60% is closer to 50% than it is to 80%, more of the lower concentration will be needed.
A science teacher has a supply of 50% sugar solution and a supply of 80% sugar solution. How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment
70 ML of the 50% solution and 35 ML of the 80% solution
35 ML of the 50% solution and 70 ML of the 80% solution
70 ML of the 50% solution and 70 ML of the 80% solution
35 ML of the 50% solution and 35 ML of the 80% solution
