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

.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.
