Answer 8

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?

Answer 9

The answer is 70 ML of the 50% solution and 35 ML of the 80% solution

Answer 10

.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.

1) You DON'T give medals for people who just give you answers. This behavior is quite inconsistent with the Code of Conduct.
2) Personally, I would not ever give a medal to someone who asks for it. But, that's just me. There's no rule for that.
